AmScope SM20 Barlow Lense/Auxiliary Lense with 2X Magnification and 48mm Mounting Diameter

This auxiliary lens for stereo microscopes doubles the overall magnification while cutting the field-of-view in half, and decreasing the working distance. The 48mm mounting thread is compatible with our SM, SW, ZM, and GM400 series microscopes. When used with an SM series microscope, the standard 100mm working distance will be decreased to 30mm.
