This is a brand new, factory sealed, Variscope Series 824 microscope. The Variscope microscope family of optical instruments is made by one of the largest "private label" optical fabricators in the world. This microscope is designed for professional grade viewing of a wide range of specimens. This microscope is manufactured with a .7x to 4.5x stereo zoom objective made from premium ground optical glass. Used in conjunction with the two sets of included ultra-wide field stereo eyepieces 10x and 20x power, along with a .5x auxiliary objective, you can achieve a zoom magnification range of 3.5x through 90x right out of the box. With the included .5x auxiliary objective, you increase the working distance to 150mm and dramatically increase the field of view so you can see more of the specimen. This is a professional grade boom stand that is designed to be completely stable even when extended to its outer range. The 10 x 9.5 inch base piece alone weighs over 24 pounds and is stable as a rock. This stereo microscope also has ergonomic features to make your microscope viewing as comfortable as possible. The main microscope head swivels 360 degrees for viewing from any angle, and the head itself sits at a comfortable 45 degree incline. The eyepieces sit in a gemel type assembly, allowing for maximum flexibility in adjusting the interpupillary distance. There are dual diopter focusing adjustments, and molded rubber eyecups are provided for your comfort. The focusing and zoom knobs are on both the right and left side of the scope allowing for easy adjustment with either the right or left hand. In addition, the entire microscope head mounts on a height adjustable base, allowing the entire scope head to be adjusted higher or lower to accommodate very large specimens. A plastic dust cover large enough to cover the entire microscope when mounted on the boom is included.

This ergonomic microscope delivers a 20X and 40X magnification that allows you to detect hard to see strain areas in gemstones or for use in identifying natural stones or to differentiate them from their synthetic counterparts. This microscope has a field view of 10 mm at 20X and 5mm at 40X. This microscope features a rheostat which controls light intensity. Its optic head is fully rotating 360°. You don't have to lose quality when you pay less. It has both a dark-field and bright-field illumination. The illumination is 2-way (transmitted and overhead). The following items are included: Wire Stoneholder, Eyeguards, and Dust Cover. The Field of View is 10mm at 20X and 5mm at 40X. The optical head rotates 360 degrees.

The Reticle Type A for MACROSCOPE 25 units provides measurements in inches and millimeters in 5/16 inch and 1 mm increments. A set of jewelers screwdrivers (not included) are required to change the reticle. For those uncomfortable in disassembling their MACROSCOPE, RF InterScience Company provides this service at an additional fee with one day turnaround in most cases.

This is a brand new, factory sealed, Variscope Series 821 microscope. The Variscope microscope family of optical instruments is made by one of the largest "private label" optical fabricators in the world. This microscope is designed for high quality viewing of a wide range of specimens. This microscope is manufactured with an internally rotating dual 1x - 3x stereo objective made from premium ground optical glass. Used in conjunction with the included wide field 10x stereo eyepieces and 20x eyepieces, you can achieve magnifications of 10x, 20x, 30x, and 60x right out of the box. The main microscope head swivels 360 degrees for viewing from any angle, and the head itself sits at a comfortable 45 degree incline. The eyepieces sit in a gemel type assembly, allowing for maximum flexibility in adjusting the interpupillary distance. The right eyepiece holder includes an independently controlled diopter focusing adjustment, and molded rubber eyecups are provided for your comfort. The focusing knob is on both the right and left side of the scope allowing for easy adjustment with either the right or left hand. 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 microscope has a trinocular viewing port to allow for attachments of cameras, dual viewing equipment and CCD video cameras. The working distance between the objective turret and the specimen is 110 mm. Working distance increases when using the 0.5x Aux. Objective. The microscope base comes with a frosted glass specimen plate and also a reversible black & white specimen plate.
