AmScope B570 Series Research Grade Semi-Plan Lab Biological Binocular Compound Microscope with 3W LED Koehler Illumination, 3D Mechanical Stage and Optional Digital Camera
The B570 is designed for biological applications in professional and educational settings. Its infinity-corrected optical system ensures reliable, low-distortion magnification, with semi-plan, achromatic corrections for accurate colors and improved sharpness. The powerful LED illumination system provides bright, evenly-distributed light for maximum contrast and definition. This model is a popular choice for veterinarians and university laboratories. The binocular head features super-widefield optics which provide a 30% larger field-of-view compared to 23mm optical systems. This lets you see more specimen at any magnification. The binocular viewing tubes use Siedentopf spacing adjustment to easily fit any user. 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 to view from different positions. 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, 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. A large translation range provides plenty of movement for larger slide-mounted 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. Built on Koehler illumination principals, the sub-stage lighting provides evenly-distributed light for optimal contrast. The powerful sub-stage LED light-source ensures cool, energy-efficient illumination with low heat for live specimens. The bright 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, 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.
