Levenhuk 900B Optical Microscope
Levenhuk 900B Binocular Microscope is designed specifically for laboratory research. It provides magnification from 40 to 1000 times, has a powerful LED backlight and allows for bright-field research: in transmitted light and using oil immersion. The capabilities of the optical device will be appreciated by professionals working in various fields of science. The microscope can also be used to teach college and university students. The binocular head can be rotated 360°. Thanks to the visual part tilt of 30°, the microscope is convenient for long-term observations. The optics are made of glass, the eyepieces are wide-field, and the lenses are achromatic. The magnification of the microscope ranges from 40 to 1000 times. The highest magnification lens, 100x, can be used for oil immersion; the 40x and 100x lenses have front lens protection (spring frame). You can adjust sharpness using the coarse and fine focusing knobs. The object table is equipped with a specimen guide, which simplifies the work with microspecimens. Directly below the table is a classic bright-field Abbe condenser with an iris diaphragm. You can install a filter in a special holder. The backlight is located at the bottom, the lighting source is a powerful 3-watt LED, there is a collector. The brightness of the backlight is adjustable; the LED requires an AC connection to operate.
