The B800 is a robust, high-performance microscope for professionals in various optical-system in a robust, upright design. With a wide range of contrast-enhancing methods available , ergonomically-designed controls, and comfort-features, this platform will serve many fields from medicine to research. The infinity-corrected, plan-achromatic optics provide high-resolution images with edge-to-edge sharpness, and optional apochromatic and semi-apochromatic objectives are available for improved resolution and transmittance. The Koehler illumination-system is designed for precision, with a variable-NA swing-condenser allowing the use of high and low magnifications with full, even coverage. Viewing Head The microscope's head is designed for precision and comfort. The super-widefield optics provide a larger field-of-view so you can see more specimen at any magnification. Compensation-free Siedentopf interpupillary adjustment allows any user to properly align the oculars without readjusting focus. For users with astigmatism or asymmetrical vision, the left ocular can be adjusted to fine-tune focus. The head is set to a 30° incline which is ideal for viewing from a standing position, and it can be rotated 360°. The quintuple objective turret provides instant access to 5 magnification levels to easily focus in on minute details from 40X to 1000X. This covers magnifications needed for studying hair follicles, cells, soil, 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 Stage The 2-layer mechanical stage provides smooth and precise movement for examination of specimen slides, with a large translation range for viewing larger samples. 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. Symmetrical focus controls are coaxially mounted for fast, intuitive focusing. Tension control lets you customize the feel to further enhance your workflow. Koehler Transmitted Illumination Built on Koehler illumination principals, the sub-stage lighting provides evenly-distributed light for optimal contrast. The rear-mounted 3W LED light-source ensures cool, energy-efficient illumination with low heat for live specimens. The bright light-source is daylight-balanced to produce natural. The light condenser uses a swing mechanism for optimized lighting at both high and low magnifications, with a NA0.22 setting for full coverage at extremely low magnifications. An iris diaphragm allows you to adjust the aperture 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 condenser is top-mounted for easier replacement when working with additional condensers. The illuminator's field lens provides an iris diaphragm to control light-spread, optimizing contrast and definition in specimen features.
