You can identify a high magnification lens by the blue band around the housing of the lens. Typically, compound microscopes come with a 40x lens. However, there are cases when this is not true. For example, you might buy a microscope with a high magnification lens of 60x or more.

Most basic microscopes do not come with an oil immersion lens, and this is because most leisure microscopy experiments do not require them. These lenses can reach up to 200x or more magnification with a 10x eyepiece lens and a 200x objective lens. You can find this lens by a white or cream-colored band around the lens.

C- and CS-mount lenses are both threaded lens mounts found on most industrial CCD cameras and lenses. The difference between C and CS-mount equipment is the distance between the flange of the lens (the part of the case that butts up against the camera) and the focal plane of the lens (where the CCD sensor must be positioned). This is known as the flange back distance.

Phase contrast microscopy makes translucent specimens easier to see by making the difference between the background and the foreground stronger. In a phase contrast objective, a black ring around the lens is used to control and translate changes in the phase of light rays into changes in their amplitude. In addition, the way the light rays are bent and focused gives the image seen through the eyepiece a lot of contrast.

Long-working distance objectives are made so you can see specimens even when they are farther away than usual. This is usually needed when a sample is stuck in a thick slide or is under a thick glass plate.

Meiji Techno cameras have "CS" mounts so they can also accommodate "C" mounts when a spacer is first threaded onto the camera providing the additional 5mm per the "C"-Mount specification as shown above.

This type of lens is usually used for smaller specimens, such as cells and bacteria, which cannot be seen with just the human eye. This includes molds, tardigrades, germs, and others.

As one can see, image sensors in cameras are actually quite small. The smaller the sensor, the more inherent magnification. The larger the sensor, the better the resolution with less magnification.

Low magnification objective lens typically ranges from 2x to 20x. Using a 10x or 20x eyepiece will magnify objects by 100x or 200x. This lens lets you view tiny specimens such as skin, hair, and fly legs. Furthermore, it has a yellow band that encircles the housing of the lens.

The V-5MM is included with all the CK Series Analog Video Cameras that Meiji sells and supports. The adverse result that can happen when a spacer is not installed is a phenomenon known as "vignetting".

Sensor sizes are often designated using fractions such as 1/1.8" or 2/3" which are larger or smaller than the actual sensor diagonal dimension. This sensor size designation goes all the way back to standard sizes given to Vidicon camera tubes developed in the 1940's and is unfortunately, still in use today.

Utilizing this microscope objective lens is pretty simple. Firstly, you need to adjust the scanning lens to properly focus and center the specimen. Afterward, you need to turn the objective turret clockwise to face the low magnification lens. Lastly, re-center your specimen after you’ve fine-tuned the focus with the coarse focus knob.

The use of differential interference contrast (DIC) lenses in brightfield microscopy helps to visualize transparent samples better. By providing contrast without the need for staining, DIC objectives reduce the amount of staining performed. In most cases, a DIC lens will not be present on a compound microscope for school or home use.

A c-mount adapter for your microscope without a lens in it, is merely a connector for your camera. What you'll get is a "direct image" on the monitor screen, which is more magnification than what is seen in the eyepieces due to the inherent magnification with image sensors and microscopes. While this arrangement is fine for some users, others require an image on the monitor that looks more like the Field Of View, or FOV, that is seen in the microscope eyetubes.

The simplest types of microscopes are magnifying glasses with a single convex lens (meaning both sides are curved outward). This kind of lens usually makes items look 5–10 times bigger by changing how the light gets into the human eye. Compound microscopes are used in schools, homes, and professional labs. They have at least two lenses that work together to magnify an image.

If you have a CS-mount camera and a C-mount lens, you can add a 5mm spacer to obtain the correct focus. If, however, you have a C-mount camera and a CS-mount lens, correct focus cannot be achieved.

You can purchase certain specialized microscope objectives when you want to perform advanced microscopy experiments. Here are some of the most common lenses to buy.

As image resolution is most desirable in all microscopy applications, 1/4" chips are just not well suited for microscopy while the 1/2" and 2/3" chip cameras strike a better balance between magnification, resolution and the size of the virtual image that the camera is seeing which to the eye appears much like a flashlight beam.

To compensate for too much mag or to match more closely the microscope FOV, one can use c-mounts with reduction lenses in order to adjust the field of view seen on the monitor. The reduction lens you require will depend on the chip size of your camera so if your camera has a 1/2" image sensor, you'll want the 0.45X c-mount. See the table at right for other adapter suggestions. Experienced users have an assortment of reduction lenses to accommodate different situations or specimens as c-mounts are relatively inexpensive.

Microscope lenses are pieces of glass that work in a microscope to aid magnification. Based on the lens type and power, you can magnify a specimen by up to 200x or more. How these tools work is straightforward, and this article will cover everything you need to know about them.

Microscope lenses come in different types that vary based on the magnification’s power. Here are the types of microscope objective lenses.

There is one lens above the object, called the objective lens. Also, there’s another one close to your eye (eyepiece). In some cases, each type of lens consists of various lenses. Compound microscopes can typically magnify by 10x, 20x, 40x, or 100x. However, you can find professional ones that can reach up to 200x magnification or more. There are also modern microscopes like the electron microscope for those who want higher magnification.

As new cameras come into the market each month, it is a never ending task to stay informed. Meiji Techno Co., Ltd. is committed to developing quality camera adapters for the most viable makes, models and form factors.

An optical microscope comes with lenses that change how rays of light travel through them. When light bounces off an object under a microscope and goes through the lens, it deflects toward the eye. This makes the item seem bigger than it is.

The C-mount lens specification for flange back distance is 17.53 mm, and on CS-mount lenses it is 12.53 mm. However, on Point Grey cameras, these physical distances are offset due to the presence of both a 1 mm infrared cutoff (IRC) filter and a 0.5 mm sensor package window. These two pieces of glass fit between the lens and the sensor image plane. The IRC filter is installed by Point Grey on color cameras; in monochrome cameras, the IRC is replaced with a transparent glass window. The sensor package window is installed by the sensor manufacturer. The refraction of these glass components requires an offset in the flange back distance from the nominal values.

Meiji Techno C-Mount Adapters with reductions lenses are easily removed from the optical path by simply removing the black colored lens piece and then re-attaching the camera to the tube directly when higher on-screen magnification is needed. Click HERE to try our On-Screen Magnification Calculator Page to see how different combinations of objectives, auxiliary lenses, c-mounts, camera chip sizes and monitor sizes effect the magnification seen on the monitor screen.

Due to the difference between the glass slide and the refractive indices of air, a specific oil is required to help fill the space. Without this oil, the objective lens won’t function correctly. Hence, you won’t get the appropriate magnification and resolution, leaving you with too much distortion.

A reflected darkfield objective works for darkfield microscopy. This technique produces a dark background with a strong contrast to aid in the visibility of translucent specimens. This object is designed to observe samples not dropped inside a covered slide. Reflected darkfield objectives typically have signs like BD, Neo, or BF/DF to help you identify them.

Microscope objective lenses work by changing how light goes through them. Essentially, when light shines on an object underneath a microscope, this light travels through the lens and bends toward your eyes, which makes the object bigger than it is. Remember that magnification power varies based on the type of lens and microscope, with magnification reaching 1000x and above. You can also find specialized objective lenses for advanced experiments.

This lens, in conjunction with the eyepiece lens, will provide the smallest magnification possible. For example, a microscope with a 10x eyepiece lens and a 4x objective lens will have a magnification factor of 40x. The magnification you get from this lens is similar to what you would from a stereo microscope, allowing you to study specimens like leaves and feathers. Also, the lens has a red band that encircles the housing of the lens. Scanning object lenses have low power and are typically used to scan a specimen before using higher magnifications.
