AmScope B690 Series Infinity-Corrected Binocular Compound Microscope with 20W Halogen Kohler Illumination, Oil Condenser and Optional Digital Camera

This is an upgraded B690 with both brightfield and darkfield light condensers. These versatile lighting options accommodate fixed or unfixed live cells, and provide contrast enhancement. Both condensers are designed for use with oil-immersion at high magnifications. The microscope's 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
