Levenhuk 850B Biological Binocular Microscope
Binocular head. Revolving nosepiece: 4 objectives. Magnification: 40–2000x:
Levenhuk 850B Biological Binocular Microscope is ideal for biochemical, pathologo-anatomic, cytologic, urologic, dermatologic, biologic, and general clinical research in laboratories of any medical institution. It allows examinations using the bright field method.
It also features a binocular rotatable nosepiece. Its revolving head allows positioning of four objectives, is inclined at 30 degrees and rotates 360 degrees around its axis. The microscope features the classic Koehler illumination system, with field and aperture diaphragm adjustment.
The focusing mechanism features integrated coarse- and fine-adjustment screws. Focus accuracy is achieved due to the vertical move of the stage relative to the fixed objective with use of focusing handles. Bi-coordinate stage can move in horizontal and vertical directions. The stage dimensions are 140×155 mm (5.5×6.1 in). The focusing mechanism and stage move smoothly, without jerks or backlash. Increment is 25 mm (1 in) for coarse focusing and 0.002 mm (0.00008 in) for fine focusing.
The microscope’s illumination system includes a halogen lamp 6V/20W, with smooth brightness adjustment.
