Biological fluorescence microscope
LMI BM-R Series
A modular research microscope created for safe, comfortable and efficient observation, with high-definition optics and extensive biological and fluorescence configurations.
- 26.5 mm super-wide field of view
- Flexible binocular-to-camera light splitting
- Anti-corrosive, low-position mechanical stage controls
- Motorized condenser, stage and nosepiece options
Designed for research
Comfort and control in every detail.
The BM-R’s large, double-way linear-drive stage can be controlled from either side and supports two slides for comparative study. Its anti-corrosive, anti-friction surface and arc-transition platform help improve durability and protect against impact.
A modular frame separates the cross arm from the main body, improving compatibility between biological and fluorescence systems. Low-position coaxial controls, adjustable tension and an upper limit stop provide accurate focusing and comfortable extended use.
Multiple trinocular light-splitting options direct light to the eyepieces, camera, or both simultaneously. Inverted- and erect-image heads are available for observation, documentation and motorized workflows.
