The B110 binocular compound microscope is designed for teaching demonstrations, clinical examinations, and laboratory applications. It is an ideal beginner 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 from both top and bottom angles, Abbe condenser with iris diaphragm, and Siedentopf head adjustments. Use the microscope for studying fixed or live cells, bacteria, plants, and soil, or water samples.
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 38° 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 3 magnification levels to focus on minute details from 40X to 1000X easily. Additional 25X eyepieces expand the maximum magnification to 1000X with 6 unique levels. This covers the 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 the 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 bottom 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. There is also an overhead light that can be switched on by flipping the power switch which allows you to illuminate larger subjects that cannot receive light from below such as fossils, rocks, and gemstones. Illumination is further enhanced by an Abbe condenser with an iris diaphragm, which can be dilated to limit the amount of light your subject receives.
