This BM33 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.
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.
• Bright Field Observation
New achromatic objective supply the sharp image after adjusting Iris diaphragm. You can get high resolution and contrast ratio image at low or high magnification. 1W Single LED illuminator supplies bright background. (Plan Achromatic Objectives are optional）
• High-powered single LED cold light illuminator
It maintains constant color temperature and closes to sun light. It can apply bright white back-ground. The illuminator supplies stable brightness and temperature difference never occurred even long time worked. Comparing with halogen lamp, LED has lower power dissipation. Brightness is adjustable freely by the rotatable key at lower left side.
