A simple microscope is a basic light microscope that has only one lens. The condenser part is absent in simple microscopes. They work on natural light and there is less usage of hooks and knobs for adjustments. On the other hand, compound microscopes have 2 adjustment knobs – fine and coarse. Their magnification is also higher than the simple microscope.

Disadvantages of using additional C-mount optics to modify the pixel size include the unavoidable loss of light (3-4%) due to additional lenses in the light path, as well as the potential for reduced image quality due to poorer lens quality and uneven illumination of the sensor. Therefore, it is more widely recommended to use larger format sensors, with pixel sizes appropriate for the magnification in the system, to maximize both FOV and resolution and negate the need for use of a magnifier or demagnifier in the mount.

Due to the nature of the microscope photo port (which is typically circular) and the available camera sensor field of view (typically rectangular or square), the camera FOV will never exactly match the full area possible on the microscope. Therefore, it is common practice to match the circular diameter of the microscope photo port with the rectangular diameter of the camera sensor, such as an 18.66 mm diagonal sensor used with a 19mm diameter photo port (Figure 1). A larger sensor camera could be used but then there would be vignetting at the corners of the image which is to be avoided.

Like all aspects of designing optical systems and components, the correct identification of camera mount necessary for the imaging system is critical to obtaining the best images possible devoid of artefacts with maximum resolution, magnification and FOV.

The F-mount is a unique mount in that, rather than being a thread mount, consists of a bayonet-style mount with a turn and lock tightening mechanism. The F-mount was originally developed for Nikon SLR cameras, but, due to their large diameter, the F-mount is also ideally suited for the newly developed large FOV microscopes (22 mm). F-mount adaptors permit a FOV of greater than 30 mm, and they also have a long back focal distance which allows them to be converted to C mount adaptors with the addition of an F to C adaptor ring.

There are a wide variety of different camera mount types. The most well-known scientific camera mount types are the C-, T- and F- mount. They are generally defined by their thread specifications, but most mount types also have a standard flange focal distance. Flange focal distance defines proper distance for the image to be focused on the sensor and is the distance between the flange of the lens and the focal plane of the lens (where the camera must be positioned).

A traditional C-mount adaptor is very common for connecting cameras and microscopes. These mounts have typically been used as the industry standard and are generally the lowest cost and the most effective as the microscopy manufacturing industry has standardized to this type of mount - anything different is less common.

These are basic microscopes that use light to magnify objects. The lenses in these microscopes refract the light for the objects beneath them to appear closer. The different types of light or optical microscopes are:

Some C-mounts will permit focusing which allows the eyepiece and the image to be in focus at the same time, which is a useful function called parfocality.

Available C-mount couplers generally range from 0.5x (halved) up to 2x (doubled). Camera sensor sizes can vary by a large amount (from 6 mm to 32 mm). Thus, the C-mount coupler desired will vary depending on the size of the camera sensor. The smaller the camera sensor, the more demagnification necessary to maximize the FOV. Generally, the size of the CCD as a decimal will indicate roughly what is required in the coupler magnification, for example, a 11 mm CCD requires a 0.7x mount to maximize the FOV (Table 1).

These are few applications associated with each microscope. Keep exploring BYJU’S Biology to learn more such exciting topics.

Thus, for a spherical mirror {both concave and convex), the focal length is half of its radius of curvature.

Most microscope systems, as standard, fit a typical C-mount adaptor. However, all microscope systems will have different requirements for the C-mount adaptor on the photoport side, therefore microscope C-mounts should be matched to the system itself and can not be interchanged between systems.

Firstly, it is necessary to know what type of camera the mount needs to attach to as this will generally determine what type of thread the mount should have, whether it will be a C- or an F-mount for example. As camera mounts are standardized, any C-mount camera can use any C-mount adaptor (on the camera connection side).

All C-mount adaptors provide a male thread that fits the female thread on a camera. This permits the connection of any C-mount microscope camera directly to the adaptor. All C-mount adaptors have a universal 25.5 mm diameter thread with 32 threads per inch and a flange focal distance of 17.52 mm. Because of the relatively small diameter of the C-mount connector, it is not suitable for larger sensors (22 mm).

Bestlens mount types

A 1x adaptor does not have any incorporated optics, making them cheaper than other types of mounts. In this situation the maximum camera field of view will depend only on the size of the camera sensor and the diameter of the photoport. These mounts only act as an adaptor to secure the camera to the imaging system.

If a mount is used that leads to 'over de-magnification', then the sensor size will be greater than the microscope FOV and this will lead to an artifact called vignetting (Figure 1). This leads to the visualization of the edge of the circular microscope FOV. This problem can be overcome by demagnifying less.

This extension works by intercepting user interactions, and it CAN BREAK some web pages. In these cases, just quit copy mode.

Lastly, as new, larger FOV systems are developed, camera mount technologies also must adapt to offer the best imaging possibilities under the new system configurations. The F-mount offers a larger adaptor permitting compatibility of large sensor cameras with these large FOV systems.

Although C-mounts are the most widely used mount in microscopy imaging. They are restricted to a maximum FOV of up to 22 mm FOV. Therefore, if FOVs greater than this are required the C-mount will no longer be the mount of choice.

The fine and coarse focus knobs are the adjustment knobs that are often used to focus the microscope. They are coaxial knobs. This means the focusing system of both fine and coarse focus are mounted on the same axis. There is also a condenser focus knob which moves the condenser up or down to control the lighting

Additional optics can be included to modify the effective pixel size in sample space in exchange for trade-offs with the FOV. However, where signal levels are low this should be avoided due to the potential for low quality lenses used in these adaptors and the loss of light through additional optics.

Finally, all microscopes will have different diameter photo ports and the formation of the image will occur at different distances away from the ports, so additional relay optics might be desired if the components are not carefully picked to optimize factors such as magnification, resolution, and FOV. However, where possible, additional optics should be minimized in systems as additional lenses contribute to loss of light and reduction in image quality.

Compound and dissection microscopes are the two types of microscopes that are mostly used in schools for educational purposes.

The primary function of a microscope is to study biological specimens. A microscope solely functions on two concepts – magnification and resolution. Magnification is simply the ability of the microscope to enlarge the image. Whereas the ability to analyse minute details depends on the resolution.

Figure 2: Use of additional optics in the camera C-mount. The example shows a microscope with a ~19 mm FOV. The camera example is a Teledyne Photometrics Prime 95B with a diagonal of 18.66 mm and a side length of 13.2 mm. In this case, a 1x adaptor leads to no additional magnification. If the sample was observed using a 10x objective, this would lead to a FOV of 1320 µm in sample space. If an additional 0.65x demagnifying lens were present in the C-Mount, the magnification when observing with a 10X objective would be reduced to 6.5x magnification, giving rise to a larger FOV (2030 µm in sample space), with larger effective pixels and a resolution that is approximately 1.5x worse. If a C-Mount with an additional 1.5x magnification was used and sample observed with a 10x objective, the magnification would be increased to 15x, this would lead to a decrease in the FOV, smaller pixels in sample space and a FOV of 880 µm.

A C-mount without a lens within is known as a 1x C-mount and the only function is as an adaptor for the camera to the microscope to secure the camera to the system. C-mount adaptors are microscope specific. Therefore, the lens within the C-mount is specific to the microscope that is purchased, for that reason, it is essential to pick a C-mount that is specifically designed for the microscope it is to be fitted to.

As a result of technical advancements, one can also find more efficient microscopes like scanning probe microscopes and scanning acoustic microscopes.

Recent technological advancements have led to the introduction of larger FOV microscope imaging systems which led to the need for larger format camera adaptors to permit the use of these FOVs.

Demagnification using C-mount optics allows the user to trade off sampling at a higher resolution for an increase in FOV, likewise, magnification using C-mount optics would do the opposite. A demagnification (<1x) coupler increases FOV but in doing-so increases the effective pixel size in sample space. Conversely, when a magnification coupler is used (1), this leads to a decrease in effective pixel size at the expense of a smaller field of view.

Lens MountAdapter

The T-mount system consists of the camera, a T-adaptor, a T-ring and a lens or telescope. Cameras generally do not have T-mounts, therefore T adaptors or T2 adaptors must be used. On the rear side of the adaptor, the mount would be appropriate to the brand and model camera that would attach to it and on the front of the adaptor is a female threaded connector matching the T thread of the lens.

Both simple and compound microscopes can be used for microbiological studies. Specimens like fungi and algae can be viewed under these microscopes. Microscopes can also be used to study soil particles.

The stage is where the specimen to be viewed is placed. A mechanical stage is often used when working on a specimen at a higher magnification. This is when delicate movement of the specimen is required. Stage clips are operated to hold the slide in place. To see different areas of the specimen, the observer must physically move the slide. A separate knob is present to move the slide in the mechanical stage. The aperture is a tiny hole in the stage via which the transmitted light enters the stage.

It is optimum to match the FOV of the microscope to the FOV of the camera, however, it is also possible to image with camera sensors that are smaller than the maximum FOV of the microscope. In this case, the image FOV will be smaller than the maximum available microscope FOV but this can be compensated for by using mounts with additional optics to demagnify the image.

There are several factors to consider when selecting a camera mount, particularly, the type of microscope the camera needs to mount to, the make and model of the camera being attached and whether additional optics within the camera mount are required or desired. This will help determine which type of mount is necessary.

Different microscopes will also have differences in their configuration and optics and will, therefore, have different focal points. Ensuring the correct mount is selected will also ensure that optimal image quality is obtained. If an incorrect mount is used for the microscope, things such as parfocality (ability to focus at both the eyepiece and camera) and focus will not be maintained, thus the image quality will suffer.

Table 1: Guide to matching the sensor FOV to the microscope FOV using different additional optical adaptors in the camera mounts to maximize imaging area on a microscope with a FOV of 16 mm^2.

Additional optics are often referred to as tube lenses or relay lenses and these are typically used to trade-off the FOV of the microscope, effective pixel size, and the resolution.

Microscope is a tool that produces enlarged images of small objects, allowing the observer to have an exceedingly close view of minute structures in a slide. It is primarily used for examination and analysis. Here, let us learn more about different types of microscopes and also their parts and functions.

A compound microscope is a high-power microscope that has higher magnification levels than a low-power or dissection microscope. It is used to examine tiny specimens like cell structures that cannot be viewed at lower magnification levels. A compound microscope is made up of both structural and optical components. The 3 basic structural components are – the head, arm and base.

A microscope camera mount (also known as a lens mount) is an essential piece of hardware that interfaces between a scientific imaging camera and photo port of a microscope. This is an essential interface that secures the camera to the microscope. Without the correct camera mount, a camera cannot be used correctly with a microscope system.

The ocular or eyepiece is what an observer looks through and is present in the upper portion of the microscope. The eyepiecetube clasps the eyepieces which are positioned above the objective lens. The objective lenses are the main optical lenses. They range in various magnifications from 4x to 100x and generally include 3 to 5 lenses on a single microscope. Nosepiece houses the objective lenses.

The basic objective of a microscope is to magnify small objects. More than magnification, the most important function of a microscope is to provide resolution. It should render high-quality details of the desired specimen in order to proceed with the experiment and analysis. Simple and compound are some of the earliest known microscopes that have been recently replaced by electron and fluorescent microscopes. The different types of microscopes are as follows:

An illuminator acts as the light source and is typically located at the microscope’s base. Most light microscopes operate on halogen bulbs with low voltage and also have variable and continuous lighting control within the base. A condenser is typically used to gather and focus the illuminator’s light onto the specimen. It is found beneath the stage and is often observed in conjunction with a diaphragm or iris. Iris or Diaphragm regulates the amount of light that reaches the specimen. It is situated above the condenser but beneath the stage.

Secondly, it is important to match the camera mount to the microscope system. The microscope connection end of the mount will be specific for the photo port of the microscope brand it is designed for. Therefore, different microscopes will require different mounts to ensure successful attachments and mounts cannot usually be switched between different microscope brands.

The T-mount is an unusual mount as, unlike others which are not interchangeable between manufacturers, the T-mount allows for inter-manufacturer compatibility. The T-mount offers the possibility of a single standardized mount, not only for microscopes but also for other optical equipment such as telescopes and slide duplicators.

Mounts can also be used to introduce additional optics into the light path, and there are a variety of different mounts available which can be identified by the number written on the side. These generally range from 0.35x up to 2x and trade off resolution with field of view (FOV).
