Phase Contrast-Compatible LED Light Source
Inverted Biological Microscope With Phase Contrast MI52-N
MI52-N adopts an excellent infinity optical system. The streamlined design concept and compact and stable high-rigidity body fully reflect the shock-proof requirements of microscopic operations. The ultra-long working distance focusing system can conduct contamination-free observation of cultured cells in tall petri dishes or cylindrical flasks. The lighting system fully considers heat dissipation and safety, and the ergonomic design concept makes operation convenient and the space wider.

Feature
Wide field of view eyepiece in high eyepoint:
The large field of view eyepiece provides a flat and wide field of view, reducing eye fatigue caused by long-term work; the high eye point design allows observation without taking off glasses.
Highly plan achromatic objective lens:
Excellent flat field performance and achromatic performance, flat image field, wide field of view, wider imaging range, and good imaging can be obtained under bright field and phase contrast.
Supports phase contrast LED light sources:
Long-life, high-brightness LED cold light source is uniform and stable, bright and non-glaring, with small thermal radiation, effectively reducing damage to cells and other samples; the brightness of the light source is continuously adjustable and the color temperature is constant.
