BM20 Series Biological Microscope

This BM20 series microscope with siedentopf binocular (monocular, trinocular available) is ideal for use at the senior high school and college level, or for use in veterinary and medical applications. The adjustable inter-pupillary distance ranges from 55mm to 75mm, and it offers four levels of magnification, ranging from 40x to 1000x.


Product Details

Standard DIN achromatic objectives are parfocaled, parcentered, and color-coded to provide sharp, color-corrected images. The coaxial coarse and fine focusing knobs are positioned low on the bracket, near the base, making certain that adjustments are made with maximum stability and minimum strain.

The ball-bearing driven, reversed nosepiece with internal click-stops, guarantee parcentration and repeatability with every magnification change. The double layer built-in mechanical stage with a low-positioned control knob, allows for smooth and comfortable specimen movement.
