This is a NEW Open Box Item selling at a Substantial Discount. This item has been tested and inspected and is in perfect working condition. It comes with our 5-Year Warranty. Limited Quantities AvailableAmscope 40X-1000X Binocular Koehler Microscope with achromatic corrections Sku: B690 Key Features 40X to 1000X magnification range using high-quality achromatic objective lenses. The infinity-corrected optical system reduces distortion and improves color accuracy. Achromatic color-corrected lenses produce high-resolution, high-contrast images. The Koehler illumination system provides centered, evenly-distributed lighting with a field aperture for maximum contrast and definition. The B690 is designed for professional biological applications. Its infinity-corrected optical system ensures reliable, low-distortion magnification, with achromatic corrections for accurate colors and improved 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. 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. 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.
