Levenhuk 850B Biological Binocular Microscope

The Levenhuk 850B is a binocular biological microscope with plan achromatic optics for brightfield observations in transmitted light. It is used in various types of medical centers for urological, dermatological, biological, biochemical, anatomopathological, cytological, and general clinical laboratory research.

The microscope is equipped with a 360º rotatable binocular head with a 30º inclination angle and a 4-objective revolving nosepiece. The revolving nosepiece with objectives is oriented toward the interior – the user can see the objective inserted into the optical path, and the space above the stage is free. The interpupillary distance is adjustable over a wide range. 10x eyepieces with a 22mm field of view are included in the set, which allows you to view a large area of the specimen.

The focusing of the microscope is adjusted by coarse and fine focusing knobs. The focusing knobs move the stage in the vertical plane and also move it horizontally along two mutually perpendicular axes. The stage does not have a positioning rack. The low positioned stage knob enhances the user experience. The specimen holder is designed for two samples. Thanks to the soft focusing adjustment and stage movement mechanism, it is moved smoothly and effortlessly.

The use of an LED light source increases the resolution of the microscope. The LED is mounted in the base, it is brightness-adjustable, and it lasts a long time before needing a replacement. The aperture and field diaphragms allow for the Köhler illumination method. The illuminator is powered by an AC power supply (220V power cord is included).

Caution: Please refer to the specifications table for the correct mains voltage and never attempt to plug a 110V device into 220V outlet and vice versa without using a converter. Remember that mains voltage in the U.S. and Canada is 110V and 220–240V in most European countries.
