This is an upgraded B690-PL which includes a turret phase-contrast system for live-cell analysis among other things. Designed for professional biological applications, the microscope's infinity-corrected optical system ensures reliable, low-distortion magnification, with plan-achromatic corrections for accurate colors, excellent field flatness and edge-to-edge sharpness. 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.
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.
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, with planatic flat-field correction to provide edge-to-edge sharpness.
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.
A phase-contrast kit is included with a turret condenser and 4 plan-achromatic phase-contrast objective lenses. Phase contrast is used to reveal detail in indistinct objects, such as unstained cells and microorganisms that would otherwise appear invisible. By using a combination of specialized objective lenses and a modified light condenser, these invisible objects can be visualized by manipulating variations in phase. This turret condenser allows you to easily rotate through the four phase-contrast settings (4X, 10X, 40X, 100X). Each phase-contrast setting has a centerable annulus for proper alignment. Each of the phase-ring equipped objective lenses has plan-achromatic corrections for improved color and resolution, as well as edge-to-edge sharpness.
Monitor and capture photos and videos with the included 1.2MP USB2.0 camera. The ultra-sensitive back-illuminated sensor is designed to excel at low-light imaging, making it ideal for fluorescence and darkfield microscopy. A 0.37X reduction lens is included for use with 23mm-30.5mm ports to capture more of the microscope's field-of-view. 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 software is available for Mac and Linux with essential functionality for capturing photos and videos.
