- Darkfield observation will provide contrast in otherwise indistinguishable objects such as live cells.
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. The addition of a darkfield condenser expands the range of applications to include common brightfield studies and darkfield observation of live cells.
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.
Optics
The objective turret provides instant access to 4 magnification levels to easily focus in on minute details from 40X to 1000X. This covers magnifications needed for studying hair follicles, cells, and bacteria. These high-quality lenses are achromatically corrected to improve resolution and color accuracy. Optional eyepieces are available to modify the compound magnification, providing levels up to 2500X.
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 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.
Darkfield
A dry darkfield condenser is included for darkfield observation using the 40X objective lens or lower. With a 0.9 numerical aperture, the condenser works with non-immersion lenses. The microscope's centering screws allow you to properly center the condenser for optimal contrast. Darkfield observation will provide contrast in otherwise indistinguishable objects by highlighting changes in refractive index. This is particularly useful for observing live cells including blood analysis.
