B490 Professional LED Biological Binocular Compound Microscope 40X-2000X w/3D Mechanical Stage

B490 Series Professional LED Biological Binocular Compound Microscope 40X-2000X Magnification With 3D Mechanical Stage. 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 LED sub-stage lighting provides cool, energy-efficient illumination. The light-source is daylight balanced to produce natural colors for imaging. 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.
