|Stereo microscopes, also called dissecting microscopes, are really two compound microscopes which focus on the same point from slightly different angles.
Our world today is a modern world, with new technologies that arise from old gadgets, it’s like an old dog had learn new tricks! Almost every gadget that we use everyday have been modernized, almost everything we use now are digital like digital cameras, cellular phones, computers and all sorts of things. The microscope has come a long way since its first introduction way back in Leeuwenhoek’s time. A microscope is an optical instrument used to view objects that could not be seen with the naked eye, the art and science of examining microscopic objects using a microscope is known as microscopy. A glimpse of the past, the microscope as some people know was not invented by Anton van Leeuwenhoek although he was the one to improve it, but rather by three men in Netherlands at early 1600s, they were Hans Lippershey, Hans Janssen with his son Zacharias.
Before the microscopes that scientist would use are simple compound microscopes, now there are a variety of microscopes to choose from. There is the electron microscope, digital microscopes, metallurgical microscope, dissecting microscope, binocular microscopes, boom microscope and also the stereo microscopes. All the tools you need and all the gadgets that suits your microscope needs can be seen on the World Wide Web. Our site here is all about the stereo dissecting microscope, all you need to know about this kind of microscope, you can find it here.
A stereo dissecting microscope is a microscope that has a different way of letting the user view the specimen, has different design and purpose from your simple compound microscope. This type of microscope uses two different and separate optical paths with two objective lenses and also with double eyepiece, with this the user may view the specimen in a three dimensional image. This kind of optical microscope have a 100x magnification power. And it also has great working distance and depth of field; both of these characteristics have an inversely proportional relationship with each other, so if the resolution goes up then you will not need a smaller depth of distance needed. And one thing that makes this microscope enjoyable for hobbyists is that it has a double eyepiece which reduces the eyestrain that the user will experience from a monocular type of microscope. Now you can use the stereo dissecting microscope to explore nature, protozoa, insects, coins, stamps, or almost anything you want!
Binocular stereo and dissecting microscopes are excellent tools for exploring natural wonders. Stereo microscope that can be used to show greater specimen detail during a dissection is the binocular stereo microscopes. Top lighting is the best kind to use with a dissection, as the light will reflect back up off the opaque surface of the specimen. A microscope that are designed for viewing whole objects like mineral, insects, and plant parts, although they can as well be used to view slides, are called binocular stereo microscopes. They have lower magnification power than compound microscopes, usually 20x or 30x. All of these binocular stereo microscopes have standard “rack and pinion” focusing. To be able to focus you need to turn a knob to slide the head of the microscope up and down. Our 20x Explorer stereo microscope is inexpensive, but has a large field of view and provides a clear image using only natural or room light.
Accommodating specimens up to 60 mm off-stage has a large working distance. With this, an excellent dissecting microscope is possible. The working distance is 60 mm with a 70 mm maximum specimen size off-stage. The 30x binocular stereo microscope has top lighting with a halogen bulb and provides 3D unrevised images with great resolution. Just turn the objective turret to choose 20x or 40x magnification. To be able to work it great as a binocular stereo, this and the top lighting does help. Also, it has a binocular head for extra-comfortable viewing. The deluxe 20x/40x Stereo microscope also makes a great binocular stereo microscope. It has both top and bottom lighting and more room for specimens—the working distance is 65 mm with a 55 mm maximum specimen size on-stage. An extra comfortable viewing is done by the binocular head. It provides magnification from 10 to 40 xs and every point in between just by rotating the objective tu`rret. If you’re looking for a zoom stereo microscope, the 10x-40x Stereo Zoom microscope is the most affordable one we’ve found.
This model has both top and bottom lighting and an 80 mm working distance with 110 mm maximum specimen height. Use for grade seven and up. The binocular stereo microscope does not magnify to the extent of compound microscope. The binocular stereo microscope is configured to allow low magnification of three-dimensional objects- objects larger or thicker than the compound microscope can accommodate. The microscope models we have in the Biology Department magnify from about 10X up to 40X with either variable or zoomed magnification. The opaque objects placed on the microscope stage can be directly illuminated with incident light from an illuminator. This method of illumination requires the clear glass insert in the microscope stage. Oftentimes the opaque stage insert, which has a white side and a black side, and direct lighting, is most commonly used. From the incident light or from transmitted light are the two types of light that utilizes the binocular stereo microscopes. You likely will see different types of illuminators available in lab.
