This is a brand new, factory sealed, Variscope Series 821 microscope: We have found this incredible new brand of premium quality microscopes and are now making them available for sale direct to the public with a special arrangement with the factory. The Variscope microscope family of optical instruments is made by one of the largest "private label" optical component fabricators in the world. Your microscope is made by the same technicians and on the same production line as optical instruments for the world's leading optical instrument brands. While this is the same instrument you might see in a science catalog for thousands of dollars, by developing the Variscope brand, the factory is able to sell the same product directly to us for much, much less. This microscope is brand new and has never been removed from the original factory packaging.
Ideal for Gem & Jewelry Inspection: This microscope is ideal for inspecting and grading gemstones and jewelry, including diamonds. The microscope comes with a gem and specimen tweezer clamp and a dark field condenser. The dark field condenser assures that any light emitted from the lower light source passes through the specimen for optimal viewing. That is, no light rays from the lower light source travel directly into the objective or your eye unless they pass through the specimen first. This enables you to view gemstones and other translucent objects without the visual distraction of ambient light entering your eye . . . only light that has passed through the gemstone will be visible to you.
Built-In Dual Halogen Light Source: Most of the 20x - 40x stereo microscopes available have cheap, low-grade lighting. However, this microscope has premium dual built-in infinitely variable halogen lighting. The upper and lower light sources are controlled independently. A unique feature of this microscope is that the upper light can be removed or aimed independently. This enables you to make fine lighting adjustments from above and below the specimen - a premium feature not available in cheaper models. Spare halogen bulbs are included with your microscope.
Dust Cover and More! This microscope includes a plastic dust cover to keep your microscope in clean dust-free condition. The microscope comes with a frosted glass specimen holder and also a reversible black & white specimen plate.
