LB-281 Trinocular LED Fluorescent Biological Microscope

LB-281 Trinocular LED Fluorescent Biological Microscope with Compensation Free Trinocular Head, Wide Field, Backward Quintuple Nosepiece, Kohler and LED Illumination, Infinite Plan Achromatic Objectives, (Infinity Color Corrected System) Reflected Light Source and Infinite Plan Optical System are newly developed microscopes, the microscopes use LED as the light source, the life span of the LED lamp is much longer than mercury lamp, the performance is also better.



Excellent fluorescent image with infinitive optical system.

LED illumination with 50,000 hours life span.

No need for cooling system and protection device due to LED cold light source.
