Celestron Lab's entry-level S20 Stereo Microscope is a versatile unit designed for making 3D observations of a range of subjects such as coins, plants and insects. The S20's dual eyepieces preserve stereoscopic vision, rendering images in three dimensions. It has a max magnification of 20x with a maximum working distance of 2.76""; more than enough to clearing view the finest details. The head and nosepiece are attached to the central pillar. Both sections are easily adjusted to set the correct working distance, achieving the sharpest focus. An energy-efficient LED emitter will illuminate your subject from above, and the microscope is battery powered so can be used in the field.
