B490B-E5
40X-2000X Binocular Biological Compound Microscope + 5MP Digital Eyepiece
United Scope
DESCRIPTION
The B490 is our hardest-working go-to microscope. The top choice for veterinarians, breeders, and clinics, this instrument has proven reliability and optical quality. It boasts features such as a compensation-free Siedentopf head, smooth stage translation, and a precision focus system with easy tension-adjustment and vertical-lock.
The 490 series offers a wide range of optional accessories to expand the functionality. The magnification range can be expanded with a large selection of objective and ocular lenses. Specialized condensers are available for dark-field and phase-contrast applications, ideal for bloodwork, fluid-analysis, and pathology.
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 both ocular tubes 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 20X eyepieces expand the maximum magnification to 2000X with 8 unique levels. This covers magnifications needed for studying hair follicles, cells, and bacteria. These high-quality lenses are achromatically corrected to improve resolution and color accuracy.
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.
The halogen sub-stage lighting provides bright illumination with excellent color rendering. The warm lighting is better suited for prolonged use, causing less eyestrain than LED and fluorescent lighting. 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 movement for precise height adjustment.
Monitor and capture photos and videos with the included 5MP digital eyepiece camera. The compact, lightweight camera can be used in place of an eyepiece to watch live images, and to record photos or videos on your computer. This ability to view microscopic images on your computer reduces eye-strain, and allows groups of people to view images at the same time. Our 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 our software is available for Mac and Linux with essential functionality for capturing photos and videos.
