Biological microscope Levenhuk 850B

Binocular Microscope Levenhuk 850B is ideal for use in the life sciences and laboratory studies. The microscope allows observation by use of both bright and dark field. Levenhuk 850B is equipped with a rotatable binocular head that can be tilted at an angle of 30 degrees and rotate 360 degrees, allowing you to select one of four lenses, lighting system according to Koehler with adjustable aperture and control the amount of light falling on the sample, variable magnification of 40x to 2000x and a movable table with dimensions 140x155 mm.

Binocular microscope Levenhuk 850B has an integrated control system: the range is 25 mm (1 inch) in the case of coarse and 0.002 mm (0.00008 inches) for precise adjustment. The lighting system of the microscope is a halogen lamp 6 V/20 W with continuously adjustable brightness, so get as much light as required by observation. Darkfield condenser is built into the microscope and can be used to observe the dark field method. This method is necessary for the observation of transparent samples that are not visible using bright-field method. This method is very important, for example, in clinical hematology. Change the method is done by rotating the ring illuminator.
