Variscope 3.5x to 90x 'Zoom Pro' Series Stereo Zoom Trinocular Microscope

Premium Features for High Quality Stereoscopic Imaging: 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. We offer a range of optional eyepieces and objectives as well. Threaded auxiliary objective lenses are also available in 1.5x and 2.0x powers for even more options with a maximum range of 3.5x to 180x magnification possible. This microscope has a trinocular viewing port to allow for attachments of cameras, dual viewing equipment and CCD video. A CCD adapter and a 23.2mm adapter are included with this microscope. This means that you can use this trinocular port with a standard or CCD mounted Variscope Digital Microscope Camera, right out of the box. In addition, you can add a T-Mount compatible Photo Adapter Tube (part #827921) if you want to attach your SLR camera to the trinocular port (you will need a camera specific "T-ring", also sold separately).

Ultra-Comfort Ergonomic Microscope Design: This stereo microscope 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 knob is on both the right and left side of the scope allowing for easy adjustment with either the right or left hand. Unlike many cheaper stereo zoom microscopes, this model allows for the continuous zoom range to be adjusted from either the left or the right side. 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.

Built-In Dual Halogen Light Source: This microscope has 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. This microscope is compatible with our gem and specimen tweezer clamp (part #827902) and a dark field condenser (part #827901).
