Here’s How You Use A Video Zoom Microscope
First of all, many people wonder what exactly is a video zoom microscope. It is a system that comes with one CCD camera which is mounted into the microscope. This suggests that the output from the eyepiece is displayed in the monitor or the CCTV. The microscope is generally tube-shaped and it allows the light to enter from one end and the camera is mounted on the opposite end.
Do not be confused with the contraption. You just have to know your way around it. In the middle of the video zoom microscope are the zoom optics. Generally, the zoom magnifications range from 0.7 up to 4.5x. Once the video image has been displayed on the CCTV screen, the size may appear rather large because the magnification is increased.
Also take note that the ccd chip size which is located inside the ccd camera greatly affects the over-all magnification. Take for example this scenario, a quarter of a size inch chip will appear to be larger than 1/3 chip, correct? The key here is knowing that the larger the size of the chip, then the more expensive the video zoom microscope is.
Users of the video zoom microscope must also be aware of the video resolution. They should know that this is primarily dependent on the camera. Generally, the cameras with higher qualities give off higher lines of resolution. The cameras can be black and white or colored. The black and white cameras clearly have more resolution compared to the colored ones because they do not have that much color information in their systems.
The Barlow lens can be placed on the bottom of the tube in the microscope in order to decrease or increase the magnification of the video. There are also a lot of c-mounts, devices that are attached to the ccd camera, that can be placed on top as well. These accessories can magnify the specimen at any angle and can also decrease or increase the magnification of the video.
A video zoom microscope has imaging systems that can offer the optical quality as well as the mechanical flexibility that you need. Each system comes with a wide range of adapters to its lenses as well as attachments in order for the user to choose which magnification is best suited for the subject that is going to be viewed. A video zoom microscope can also adjust to the working distance as well as the field of view that the user needs in order to capture the best image of the specimen that is being observed.
All the user has to do with his video zoom microscope is to adjust the parfocal zoom lens system to meet the total magnification range that will closely benefit the monitor attached to the system. He must learn how to measure the working distances (in terms of inches) as well as the fields of view (in terms of mm.)
The video zoom microscope is perfect for closely inspecting products like PC boards, semiconductor chips, watch parts and tool bits. These increase the productivity of the observer by decreasing eye fatigue as well as operator stress, which is often obtained when using stereo microscopes and binoculars. Therefore, video zoom microscopes have been quite popular in the mentioned industries because they are very easy to use and they also display clear and crisp images on the CCTV monitor which is perfect for individual, as well as group viewing.
Video Zoom Microscopes reach the condition where in the magnification range depends on the lens attachment and the adapters. Therefore, the user must know where to position the system in order for it to reach the right telecentrity and to have constant perspective as well as the maintenance of the magnification.
There are some video zoom microscopes that contain ultra high magnification optics which are perfect for quality control and video inspection. These come with HCVR or High Contrast Video Response to clearly show images from the eyepiece to the monitor in colorful and match-worthy surfaces. The manufacturing and optical designs of video zoom microscopes benefit the user as well as the onlooker, primarily because of the crisp and clear images that result to better viewing.
Video microscopy also inspects the high power and the low power biological microscopes which are used to conduct scientific studies and research. By viewing these in the monitor attached to the system, it saves the user from neck and back strain as opposed to screening the specimen through scope binoculars.
