Overview


Key Features:

  • 40X to 2000X expanded magnification range using high-quality, color-coded objective lenses, and 10X and 20X eyepieces for eight unique 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 2-layer mechanical stage with low-position controls, and coaxial coarse and fine focus for ergonomics and an efficient workflow.
  • Cool, energy-efficient LED lighting produces daylight-balanced illumination for natural colors.

The M250 monocular compound microscope is small, but it packs a big punch. The sleek, compact design uses a minimal footprint while providing high-efficiency features like coaxial coarse and fine focus, a 2-layer mechanical stage, a height-adjustable Abbe light-condenser, and a reversed lens turret which maximizes the stage's working space. The microscope is perfect for classroom workstations or labs with limited space.

The monocular head keeps things simple. The use of a single eyepiece means that no adjustments are necessary for eye alignment or symmetrical focus. The head can rotate 360° for viewing from different positions. Interchangeable eyepieces allow you to change the overall magnification with optional lenses, or use a camera in place of the eyepiece to view microscopic images on a computer monitor or other display.

The objective turret provides instant access to 4 magnification levels to easily focus in on minute details from 40X to 1000X. An additional 20X eyepiece expands the maximum magnification to 2000X 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.
