- The Koehler illumination system provides centered, evenly-distributed lighting with a field aperture for maximum contrast and definition.
This an upgraded version of the B660, adding a darkfield light-condenser for professional biological applications including darkfield observation. It uses an ergonomic design for comfort and a fluid workflow, and its achromatic optics provide sharp, color-correct images. The halogen illumination system provides low-fatigue, evenly-distributed light for maximum contrast and definition. This model is a popular choice for veterinarians and university laboratories. Specialized darkfield optics allow you to observe live cells including blood and other fluids, making it a great choice for clinics and medical labs.
To customize the microscope to your viewing comfort, the eyepiece spacing can be easily adjusted using a precision Siedentopf mechanism. A diopter is comes 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.
The objective turret provides instant access to 4 magnification levels to easily focus in on minute details from 40X to 1000X. Additional 15X eyepieces expand the maximum magnification to 1600X with 8 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 large 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.
Built on Koehler illumination principals, the sub-stage lighting provides evenly-distributed light for optimal contrast. The halogen light-source provides bright illumination with a lower color-temperature for decreased fatigue when used for long periods. 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 height adjustment for precision control, and is centerable for proper alignment. The illuminator's field lens provides an iris diaphragm to control light-spread, optimizing contrast and definition in specimen features.
An oil darkfield condenser is included for darkfield observation using high-power objective lenses. The condenser is designed for use with immersion oil, and can accommodate higher numerical-aperture lenses. 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.
