Magnification: 40–1000x. Infinity plan achromatic objectives, light source – LED 3W, stage with two specimen holders, Köhler illumination
The Levenhuk 870T is a trinocular biological microscope for brightfield observations in transmitted light. It is used in different types of medical centers for urological, dermatological, biological, biochemical, anatomopathological, cytological, and general clinical laboratory research. The microscope can be equipped with a digital camera to output images to an external screen, take photos, and record video. The camera must be purchased separately and is installed in the trinocular tube.
The head can also be tilted 30°. This tilt is comfortable for long-term work. The interpupillary distance is adjustable. The eyepieces have a wide field of view, and so it is convenient for the user to work with large samples. Four plan achromatic objectives are mounted in a revolving nosepiece that is oriented toward the interior. In this position, you can see the objective, and the space above the table is free.
There is no positioning rack on the stage and that improves the ergonomics of the device. The horizontal stage knob is located low for user comfort. The specimen holder is designed for two samples. The focusing knobs allow for coarse and fine focusing adjustment. All of the stage movements are smooth with no jerkiness.
The light source is located under the stage and the Abbe condenser. The LED is brightness-controlled and is powered by 220V. Thanks to LED illumination, the resolution of the microscope is higher than that of analogs with halogen bulbs. Both aperture and field diaphragms make it possible to set up the Köhler illumination.

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.
