There are three usual ways of doing this. Let’s take a brief look. The first uses optical lenses designed to give a video camera variable magnification. Dissecting zoom microscopes can greatly enhance the ability of a researcher to record his findings by allowing the alteration of an image size from the microscope to a video monitor. This is the best way to achieve dissecting zoom microscopes. It is possible with some optical lenses to add a motor that turns the zoom knob for you so you have an automatic zoom function, but this gets rather expensive. It’s usually only done for remote applications. This gives an imitation zoom that works fairly well with some video relay lenses. Since video cameras were first added to microscopes, this has been a simple but effective means of getting a variable image size onto a television monitor. Another way to get set up zoom microscopes is to alter the plane of the CCD video chip, which is the camera itself, on a vertical plane over a video relay lens. You can move a camera vertically over a relay lens with the camera’s c-clamp onto the video itself.
These systems work satisfactorily up to about 50 percent of the total zoom range available. The last zoom technique is actually a function of the digital electronics included with some cameras. By depressing the zoom button on the camera, the image is digitally magnified. Beyond that, the digital image starts reflecting the fractal imperfections of the digital enhancement with jagged edges–so you don’t have a clear image. Although dissecting zoom field microscopes are ideal as clinical microscopes, people like to use them for a lot of different purposes because they give such crisp, clear three-dimensional images. This also allows for a good level of versatility in the types and sizes of specimens that can be examined. You can get a range of different sizes of boom stands. Many dissecting zoom microscopes are available in a range of different configurations. There is the basic adjustable pole stand, which allows for a great deal of versatility.
Then there’s the adjustable boom stand. Then, you can get the standard adjustable stage. This allows for less adaptability, but if you’re only examining slides, this will probably be the easiest configuration for you. Note that, especially with dissecting zoom microscopes, base fluorescent lighting can create an unclear image, and so halogen will give a crisper image. You can get a basic dissecting zoom microscope that needs no electricity and will therefore be great for work outside a lab setting. At the other end of the range, you can get a mobile, floor mounted stereo dissecting zoom microscope that is suitable for a range of demanding uses such as forensics, medicine, veterinary sciences and so on. It can also be used for watch mending and other precise technologies. Floor standing dissecting zoom microscopes are admittedly expensive; expect to pay over a thousand dollars! But you can get many great models of dissecting zoom microscopes that fall between the two models I’ve just talked about, giving amazing performance for just a few hundred dollars. Once you’ve decided which features you really need, you can choose your model accordingly.
