Welcome to Dissecting-Microscopes
Stereomicroscopes are designed for viewing whole objects such as minerals, insects, and plant parts, although they can also be used to view slides. They have lower magnification power than compound microscopes, usually 20x or 30x. Dissecting microscopes are stereomicroscopes that can be used to show greater specimen detail during a dissection. 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. All of these stereomicroscopes have standard “rack and pinion” focusing. To focus, you just turn a knob to slide the head of the microscope up and down. Stereo and dissecting microscopes are excellent tools for exploring natural wonders.
Our 20x Explorer stereomicroscope is inexpensive, but has a large field of view and provides a clear image using only natural or room light. It has a large working distance, accommodating specimens up to 60 mm off-stage. This makes it an excellent dissecting microscope as well. The working distance is 60 mm with a 70 mm maximum specimen size off-stage. This and the top lighting make it work great as a dissecting microscope. Also, it has a binocular head for extra-comfortable viewing. The deluxe 20x/40x Stereomicroscope also makes a great dissecting microscope. The 30x Stereomicroscope 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. 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.
Its binocular head makes viewing extra-comfortable. If you’re looking for a zoom stereomicroscope, the 10x-40x Stereo Zoom microscopes is the most affordable one we’ve found. It provides magnification from 10 to 40 xs—and every point in between—just by rotating the objective tu`rret. This model has both top and bottom lighting and an 80 mm working distance with 110 mm maximum specimen height. Its binocular head makes viewing extra-comfortable. Use for grade seven and up. We also sell a Digital Stereo Zoom microscope. Furthermore, the two separate lenses of the binocular dissecting microscope allow one to see objects in three dimensions, i.e., in stereo. Dissecting microscopes do not magnify to the extent of compound microscopes.
The dissecting 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. Dissecting microscopes utilize two types of light: from incident light or from transmitted light. 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. However, in most instances the opaque stage insert, which has a white side and a black side, and direct lighting, is most commonly used. You likely will see different types of illuminators available in lab. In this case the illuminator can be mounted in an opening in the arm of the microscope, or in an adapter ring attached to a separate illuminator base. Alternatively, light from a source such as a lamp can be reflected through a translucent object from underneath using the sub stage mirror.
