Overview


40X-2500X Binocular Biological Compound Microscope

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 top choice for veterinarians, clinics, and classrooms, this microscope provides high quality optics and precision mechanics.
  • The 2-layer mechanical stage with low-position controls, and coaxial coarse and fine focus promote an efficient workflow.
  • Halogen lighting reduces eye-strain for prolonged use.
  • A large compliment of optional accessories are available for darkfield, phase-contrast, and fluorescence.

This professional binocular microscope is designed for teaching and clinical use. Its high quality optics and precision mechanics have made this model a favorite for veterinarians and clinics. It has a large compliment of optional accessories for darkfield, phase-contrast, and fluorescence.

The binocular head can be customized for each user, with a sliding interpupillary adjuster for varying eye spacing, and diopters for both eyes to fine-tune focus for nearsighted users and for asymmetry. The head can be rotated 360°, and has a 45° incline for viewing while seated or standing. Interchangeable eyepieces allow for an expanded magnification range, or the use of special eyepieces with pointers and measuring reticles.

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. 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 halogen sub-stage lighting provides bright illumination with excellent color rendering. The warm lighting is better suited for prolonged use, causing less eyestrain than LED and fluorescent lighting. 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 movement for precise height adjustment.
