This is a brand new, factory sealed, Variscope Series 862 microscope. The Variscope microscope family of optical instruments is made by one of the largest "private label" optical fabricators in the world. Included are three multi-coated objective lenses. These achromatic lenses are specially designed to correct color aberrations and display a true-color image. 4x, 10x and 40x (spring loaded) objectives are included. A single 10x eyepiece is also included. Possible magnifications are 40x, 100x, 400x. This microscope has a monocular head that sits at a 45 degree incline and swivels 360 degrees for viewing from any angle. Independent coarse and fine focusing knobs are on both the right and left side of the scope. This microscope has a 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. There is a graduated scale printed on the slide holder. This microscope has a built-in 20 watt incandescent bulb, with adjustable intensity light controls and it has a built-in spiral-type N.A. 1.2 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. A swing-out filter holder is included as is a green viewing filter. A mirror is included and can be fitted for use as the lower light source for field applications where electric power is unavailable.
