LB-274 Binocular LED Fluorescent Biological Microscopes

LB-274 Binocular LED Fluorescent Biological Microscopes with Wide Field Infinite Color Corrected Plan Optical System, (Infinity Color Corrected System), Seidentopf Binocular Viewing Head, Infinite Plan Achromatic Objectives, and Abbe Condenser (Anti-Fungus) are newly developed microscopes with an infinity color corrected system, 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.

 

Features

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.

465-476nm excited wavelength with high SNR.

Convenient to use, no need warm-up.

More fluorescent filters are available for different applications.
