40x-2000x Trinocular Biological Compound Microscope

This is a brand new, factory sealed, 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 20x eyepieces. This allows for magnification ranges of 40x, 80x, 100x, 200x, 400x, 800x, 1000x, and 2000x. 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. Unlike most cheaper models on the market that have simple slide clips, this microscope has a 115mm x 125mm stage with a fully mechanical X-Y axis slide holder. With this functionality, you can easily move the slide around on the stage with fine precision, no fumbling the slide under the clips. This model includes a trinocular imaging port to allow for the attachment of a film camera, digital camera, or CCD camera. A 23.2mm ocular adapter and a C-mount (CCD) adapter are included with the microscope. T-mount (T-ring) photo adapters are available. This microscope has a built-in 20 watt halogen bulb, with adjustable intensity light controls. Cheaper models 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 for precise control over the amount and focal length of light aimed at your specimen. A swing-out filter holder with blue and green filters is included.
