While most microscope objectives are designed to work with air between the objective and cover glass, objectives lenses designed for higher NA and greater magnification sometimes use an alternate immersion medium. For instance, a typical oil immersion object is meant to be used with an oil with refractive index of 1.51.

Both the objective lens and the eyepiece also contribute to the overall magnification of the system. If an objective lens magnifies the object by 10x and the eyepiece by 2x, the microscope will magnify the object by 20. If the microscope lens magnifies the object by 10x and the eyepiece by 10x, the microscope will magnify the object by 100x. This multiplicative relationship is the key to the power of microscopes, and the prime reason they perform so much better than simply magnifying glasses.

Optical fiber cables consists of a glass core and plastic cladding and have the capability to carry thousands of voice calls. Fiber optic cables provide a capacity of 1Mpbs to 100Gbps.

The optical performance of an objective is dependent largely on the optical aberration correction, and these corrections are also central to image quality and measurement accuracy. Objective lenses are classified as achromat, plan achromat, plan semi apochromat, plan apochromat, and super apochromat depending on the degree of correction.

Adapters are usually placed inside the fiber optic patch panel and are selected based on the type of fiber and connectors used in the network.

Microscope objective lenses are typically the most complex part of a microscope.  Most microscopes will have three or four objectives lenses, mounted on a turntable for ease of use. A scanning objective lens will provide 4x magnification,  a low power magnification lens will provide magnification of 10x, and a high power objective offers 40x magnification. For high magnification, you will need to use oil immersion objectives. These can provide up to 50x, 60x, or 100x magnification and increase the resolving power of the microscope, but they cannot be used on live specimens.

The LC fiber optic adapters have smaller pins and sheaths, which help increase the density and capacity of fiber optic connectors. The LC fiber optic adapter is divided into simplex, duplex, and quad.

In modern microscopes, neither the eyepiece nor the microscope objective is a simple lens. Instead, a combination of carefully chosen optical components work together to create a high quality magnified image. A basic compound microscope can magnify up to about 1000x. If you need higher magnification, you may wish to use an electron microscope, which can magnify up to a million times.

Most microscopes rely on background illumination such as daylight or a lightbulb rather than a dedicated light source. In brightfield illumination (also known as Koehler illumination), two convex lenses, a collector lens and a condenser lens,  are placed so as to saturate the specimen with external light admitted into the microscope from behind. This provides a bright, even, steady light throughout the system.

The primary and essential difference between multi-mode and single-mode is that multi-mode optical fibers has a larger core and will not carry data as far as single-mode fiber. The multi-mode optical fibers are used in internal networks where single-mode is used in outdoor applications

Optical fiber cables are made from a set of fibers with a thin glass or plastic strand to provide a speed of 1Mbps to 100 Gbps and carry plenty of data. When you use optical fiber cables in LAN for distance extension, multiple factors are at play. For example, which type of optical fiber cable connector is practical for your network device or which type of connector your devices support.  If you would like more information, Omnitron Systems’ technicians are always available to help and answer your questions. Contact us today

The eyepiece or ocular lens is the part of the microscope closest to your eye when you bend over to look at a specimen. An eyepiece usually consists of two lenses: a field lens and an eye lens. If a larger field of view is required, a more complex eyepiece  that increases the field of view can be used instead.

The parfocal length of a microscope is defined as the distance between the object being studied and the objective mounting plane.

This guide discusses all parts of the fiber optic cables: the layers, connectors, adapters, and types. Stay with us to learn how to use these fiber optic cables in LAN and WAN applications.

There are some important specifications and terminology you’ll want to be aware of when designing a microscope or ordering microscope objectives. Here is a list of key terminology.

FC fiber optic adapters have both single-mode and multi-mode versions, but they are mostly used in single-mode applications, high-speed fiber-optic telecommunication networks, and high vibration environments.

While a magnifying glass consists of just one lens element and can magnify any element placed within its focal length, a compound lens, by definition, contains multiple lens elements. A relay lens system is used to convey the image of the object to the eye or, in some cases, to camera and video sensors.

The ST fiber optic adapter has a metal and plastic body with a rectangular body cover. The ST fiber optic adapter is divided into simplex and duplex.

An microscope objective  may be either reflective or refractive. It may also be either finite conjugate or infinite conjugate.

The ST connector is used in short-distance projects, such as corporate network environments and military, as well as industrial applications. ST connectors are still the most widely used in industrial networks and the construction of multi-mode fiber applications.

A basic compound microscope could consist of just two elements acting in relay, the objective and the eyepiece. The objective relays a real image to the eyepiece, while magnifying that image anywhere from 4-100x.  The eyepiece magnifies the real image received typically by another 10x, and conveys a virtual image to the sensor.

The SC fiber optic adapter is made of metal and plastic with rectangular body covers. The SC fiber optic adapters are divided into simplex and duplex.

A reflective objective works by reflecting light rather than bending it. Primary and secondary mirror systems both magnify and relay the image of the object being studied. While reflective objectives are not as widely used as refractive objectives, they offer many benefits. They can work deeper in the UV or IR spectral regions, and they are not plagued with the same aberrations as refractive objectives. As a result, they tend to offer better resolving power.

SC fiber optic connectors are cheap, simple, and durable. They provide accurate alignment due to their ceramic ferrules.

Fiber optic cables are made of a thin strand of glass or plastic and carry data signals in the form of light waves. This allows them to carry much higher bandwidth applications than conventional cables. Optical fiber cables can easily transfer data, audio, and other data because they have up to 100 Gbps bandwidth.

Refractive objectives are so-called because the elements bend or refract light as it passes through the system. They are well suited to machine vision applications, as they can provide high resolution imaging of very small objects or ultra fine details. Each element within a refractive element is typically coated with an anti-reflective coating.

Depending on the manufacturer, the buffer layer is made of plastic, which wraps around the cladding. This layer holds the entire cable, which can hold hundreds of different optical fibers. For measurement, the cladding does not count. The decimal number 130/60 microns for fiber represents that the diameter of the core is 60 and the buffer is 130.

Optical fiber is made of several layers. The core is the innermost layer that usually consists of a fully reflective filament of pure glass, but some cables are fully reflective plastic, which reduces manufacturing costs. However, a plastic core doesn't have same quality as glass and is mostly used to carry data over short distances. The cladding is made of glass or plastic, which is located around the core. The diameter of the core and the cladding together is about 125 microns, the size of human hair.

The field of view (FOV) of a microscope is simply the area of the object that can be imaged at any given time. For an infinity-corrected objective, this will be determined by the objective magnification and focal length of the tube lens. Where a camera is used the FOV  also depends on sensor size.

Numerical aperture NA denotes the light acceptance angle. Where θ is the maximum 1/2 acceptance ray angle of the objective and n is the index of refraction of the immersive medium, the NA can be denoted by

Although today’s microscopes are usually far more powerful than the microscopes used historically, they are used for much the same purpose: viewing objects that would otherwise be indiscernible to the human eye.  Here we’ll start with a basic compound microscope and go on to explore the components and function of larger more complex microscopes. We’ll also take an in-depth look at one of the key parts of a microscope, the objective lens.

Single-mode fiber optic cables have a 9 micron core which allows data to be transmitted farther then multimode. Single-mode fiber can carry multiple wavelengths providing more devices to be connected to the same fiber optic cableing. They use laser transceivers , which is more expensive, but can transmit a longer distance (40 kilometers or more).

The working distance of a microscope is defined as the free distance between the objective lens and the object being studied. Low magnification objective lenses have a long working distance.

There are two major specifications for a microscope: the magnification power and the resolution. The magnification tells us how much larger the image is made to appear. The resolution tells us how far away two points must be to  be distinguishable. The smaller the resolution, the larger the resolving power of the microscope. The highest resolution you can get with a light microscope is 0.2 microns (0.2 microns), but this depends on the quality of both the objective and eyepiece.

A basic achromatic objective is a refractive objective that consists of just an achromatic lens and a meniscus lens, mounted within appropriate housing. The design is meant to limit the effects of chromatic and spherical aberration  as they bring two wavelengths of light to focus in the same plane. Plan Apochromat objectives can be much more complex with up to fifteen elements. They can be quite expensive, as would be expected from their complexity.

A microscope is an optical device designed to magnify the image of an object, enabling details indiscernible to the human eye to be differentiated. A microscope may project the image onto the human eye or onto a camera or video device.

Light can travel in a fiber optic cable at approximately 214,000,000 meters per second. However, the speed of the data being carried by fiber optic cabling depends on the device, so when we say light, we don't mean as fast as light itself.

In 1966, scientists were trying to find a way to transmit information by light waves for the first time, Charles K. Kao and George A. Hockham proposed the use of glass as a medium for emitting light.

Multi-mode fiber optic cables have a 50 or 62.5 micron core which restricts the distance of the data application. They use LED transceivers which are less expensive than laser optic but they limit the distance the data can travel. . Multi-mode fiber is used for short distances to connect devices in one building. The maximum distance for multi-mode fiber depends on the speed of the application (5km @ 100M, 500m @ 1G and 300m @ 10G).

Following the introduction of the design in 1970, Corning Glass researchers,  Robert Maurer, Donald Keck, and Peter Schultz, announced the construction of the first single-mode fiber optic cable. Since then, the world of communication has been changing because data has been transmitted in the form of optical pulses through fiber-optic technologies.

As fiber optic cables transmit data in the form of light, they transmit and carry much more data than copper cables, which transmit data in the form of electricity.

Historically microscopes were simple devices composed of two elements. Like a magnifying glass today, they produced a larger image of an object placed within the field of view. Today, microscopes are usually complex assemblies that include an array of lenses, filters, polarizers, and beamsplitters. Illumination is arranged to provide enough light for a clear image, and sensors are used to ‘see’ the object.

The LC fiber optic connectors are suitable for high-density environments and reduce the space required for the patch panel.

Fiber optic connectors are located at both ends of a fiber optic cable to connect to the network switches, telecommunications equipment, or even a light source. Companies have designed many types of connectors, but some of them have been more practical than others.
