Description

Selling my husband's 40x-2000x Binocular Biological Compound Microscope This is a Variscope Series 8621 microscope. The Variscope microscope family of optical instruments is made by one of the largest "private label" optical component fabricators in the world. Included with the quadruple nosepiece are four achromatic multi-coated objective lenses that display a true-color image. You get 4x 10x spring loaded 40x and spring loaded oil immersion 100x objectives included with this microscope. For viewing we provide two sets of eyepieces: a pair of premium grade wide-field 10x (18mm) eyepieces and a second set of 16x eyepieces. Ergonomic features include an advanced Seidentopf-type microscope head to provide maximum comfort in adjusting interpuplillary distance. The microscope head swivels 360 degrees and sits at a 30 degree incline. The eyepieces have diopter focusing adjustments. The independent coarse and fine focusing knobs are on both the right and left side of the instrument. Unlike cheap models with simple slide clips this microscope has a 115mm x 125mm stage with a fully mechanical X-Y axis slide holder so slides can be moved on the stage with fine precision no fumbling the slide under clips. There is a graduated scale printed on the slide holder to allow you to maintain a record of the location of various structures on a particular slide. This microscope has a built-in 20 watt halogen bulb with adjustable intensity light controls. Beware of cheaper models that use a tungsten bulb or have a simple on/off switch with no brightness controls. The microscope has a built-in spiral-type N.A. 1.25 Abbe condenser under the stage with an iris diaphragm. This advanced condenser gives you incredible control over the amount and focal length of light aimed at your specimen and is critical for high-powered magnification viewing. 3 Extra halogen bulbs included. I do not know a single thing about microscopes but questions are welcome! Thank you!
