Overview


Key Features:

  • 40X to 2500X magnification range for studying a range of specimens including hair follicles, cells, and bacteria. 10X and 25X eyepieces provide 6 unique magnification settings.
  • A sleek, compact compound microscope for students and professionals. This microscope is perfect for classroom workstations or labs with limited space.
  • Professional features include a Siedentopf binocular head for precise adjustments, a 2-layer mechanical stage with low-position controls, and coaxial coarse and fine focus for ergonomics and an efficient workflow.

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 25X eyepieces expand the maximum magnification to 2500X with 6 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.
