Levenhuk 870T Biological Trinocular Microscope
Trinocular head. Revolving nosepiece with four objective lenses. Magnification from 40x to 2000x.

Levenhuk 870T is a reliable biological trinocular microscope that may be used for the bright field observations. It is commonly used in various medical laboratories for clinical research in dermatology, biochemistry, cytology and other scientific studies. Due to the trinocular design of the head, this model may be turned into a digital microscope with an addition of an eyepiece digital camera.

The head of the microscope is inclined at 30 degrees and may be rotated 360 degrees around its axis. Four objective lenses on the revolving nosepiece, Köhler illumination method, adjustment of the aperture and field diaphragms make this microscope a perfect tool for serious observations.

The stage (140x155 mm, 5.5x6.1 in) moves along two axes. Focusing the view is achieved by rotating the coarse and fine focus wheels that raise or lower the stage itself, thus bringing the sample closer to or farther away from the objective lens. Both focus systems have smooth movements in 25 mm (1 in) increments for coarse and 0.002 mm (0.00008 in) for fine.

There is a variable brightness 6V 20W halogen lamp installed in the base of the microscope that acts as an illumination source.
