The B250 binocular compound microscope is small, but it packs a big punch. The sleek, compact design uses a minimal footprint while providing high-efficiency features like a Siedentopf head, coaxial coarse and fine focus, and a 2-layer mechanical stage. The reversed lens turret maximizes the stage's working space. The microscope is perfect for classroom workstations or labs with limited space.

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 head can also be rotated 360° to accommodate multiple users. Various eyepieces can be used to increase the overall optical magnification.

The objective turret provides instant access to 4 magnification levels to easily focus in on minute details from 40X to 1000X. Additional 16X eyepieces expand the maximum magnification to 1600X with 8 unique levels. This covers magnifications needed for studying hair follicles, cells, and bacteria. The turret's reversed orientation provides more working room above the stage. This model uses compact-format lenses to reduce the overall profile while maintaining achromatic corrections 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 uses a simple spiral-control for height adjustment, and an iris diaphragm to optimize contrast and depth-of-field.

Monitor and capture photos and videos with the included 2MP 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.
