The B120 binocular compound microscope is designed for teaching demonstrations, clinical examinations and 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, centerable condenser, and Siedentopf head adjustments. Use the microscope for studying fixed or live cells, bacteria, plants and soil, or water samples. Viewing Head 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 angled at 30° to comfortably accommodate a seated position without neck strain. Various eyepieces can be used to increase the overall optical magnification. OpticsThe 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. These high-quality lenses are achromatically corrected to improve resolution and color accuracy. The Stage 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. Transmitted Illumination 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. Digital ImagingMonitor and capture photos and videos with the included 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.
