The M620 monocular compound microscope is designed for classrooms and basic laboratory applications. It is an ideal microscope for teachers and students, including those in medical school or with a major in biology. It has a number of advancements in functionality compared to other microscopes in its class, such as enhanced LED lighting and a centerable condenser. Use the microscope for studying fixed or live cells, bacteria, plants and soil, or water samples. The monocular head keeps things simple. The use of a single eyepiece means that no adjustments are necessary for eye alignment or symmetrical focus. The head can rotate 360° for viewing from different positions. Interchangeable eyepieces allow you to change the overall magnification with optional lenses, or use a camera in place of the eyepiece to view microscopic images on a computer monitor or other display. The objective turret provides instant access to 4 magnification levels to easily focus in on minute details from 40X to 1000X. An additional 25X eyepiece expands the maximum magnification to 2500X with 6 unique levels. This covers magnifications needed for studying hair follicles, cells, and bacteria. 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 LED sub-stage lighting provides cool, energy-efficient illumination. The light-source is daylight balanced to produce natural colors for imaging. With our specially developed fly-eye lens, the light is evenly distributed at maximum brightness to improve contrast and resolution. Illumination is further enhanced by a centerable Abbe condenser, which can be realigned for any magnification to guarantee proper lighting. Monitor and capture photos and videos with the included 1.3MP digital eyepiece camera. The compact, lightweight camera can be used in place of an eyepiece 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. 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.
