This is a binocular 20W Halogen compound microscope designed for clinical examination and teaching demonstration in medical field, laboratories and colleges. It comes with compensation-free binocular head, mechanical stage and 20W Halogen illumination system.

To customize the microscope to your viewing comfort, the eyepiece spacing can be easily adjusted using a precision Siedentopf mechanism. A diopter is available on the left ocular tube to compensate for asymmetry, and the ocular tubes are ang20W Halogen at 30° to comfortably accommodate a seated position without neck strain. Various eyepieces can be used to increase the overall optical magnification.

The objective turret provides instant access to 4 magnification levels to easily focus in on minute details from 40X to 1000X. Additional 25X eyepieces expand the maximum magnification to 2500X with 6 unique levels. This covers magnifications needed for studying hair follicles, cells, and bacteria. The turret's reversed orientation provides more working room above the stage. These high-quality lenses are achromatically corrected to improve resolution and color accuracy.

The 2-layer mechanical stage provides smooth and precise movement for examination of specimen slides. The stage's low-position controls are conveniently placed near the coaxial focus knobs for a streamlined workflow. Examining specimen slides is intuitive and precise for users at any skill level.

The 20W Halogen sub-stage lighting provides cool, energy-efficient illumination. The light-source is daylight balanced to produce natural colors for imaging. The Abbe light condenser has a high 1.25 numerical aperture for oil-immersion, and an iris diaphragm to optimize contrast and depth-of-field. The condenser holder uses rack-and-pinion movement for precise height adjustment, and has two centering screws to properly align the condenser.

Monitor and capture photos and videos with the included 9MP USB2.0 camera. The C-mount camera is specially designed for use with microscopes, allowing you to watch live images, and to record photos or videos on your computer. This ability to view microscopic images on your computer reduces eye-strain, and allows groups of people to view images at the same time. A 0.5X reduction lens is included to capture more of the microscope's field-of-view. Our professional software for Windows provides a wide assortment of capture and photo-editing functions including color correction, time-lapse capture, image stitching, and a full complement of measuring tools. A lite version of our software is available for Mac and Linux with essential functionality for capturing photos and videos.
