Zoom stereo microscope focuses on producing stereo images while the sample is viewed through a microscope. The zoom know on the design provides a large scale magnification and has ability to review each magnification of a microscopic sample in detail. The magnification can be multiplied using a dual eyepiece. These microscopes are generally used to view macro samples at an enlarged level and shows clear up-right picture. The enlarged magnification is possible as the light reflected is transmitted through the specimen rather than reflecting from the surface.
