Unmatched plan optics and the finest mechanics comprise the ergonomic engineering this professional trinocular compound microscope. The Siedentopf binocular head with two comfortable viewing 20 mm eyepieces affords an expanded field of view and 360° rotation. Dual diopters compensate for discrepancies between your eyes while 55-75 mm interpupillary adjustment allows each user to achieve a custom fit. A third vertical 20 mm eyepiece/eyetube with diopter creates a trinocular head, and makes this a great teaching microscope; you can even mount this trinocular microscope with one of our digital USB cameras! Its DIN standard plan objectives and overall high-quality optical system provide flawless clarity, flatness of field, and true color at 40x, 100x, 400x, and 1000x magnification, while keeping 95% of the field of view in focus at once.

This compound microscope has effortless coaxial fine and coarse focusing and low-position stage controls, which allow continuous accuracy with fingertip precision. Compare slides side-by-side on the extra-large 50 x 75 mm integrated mechanical stage. Includes 1.25 N.A. Abbe condenser, an iris diaphragm, and premium 20-watt extra bright variable-intensity halogen lighting for ideal contrast control. This professional microscope is proficient in all biology, medical or veterinary laboratory applications. Other industry-standard features include: ball-bearing, double-layer mechanical stage; swing-out filter holder with blue, green, and yellow filters; and 100-240 volt AC universal power supply.

This trinocular microscope comes complete with instructions, a dust cover, a spare bulb, immersion oil, and a lifetime warranty.
