L3201A(LED) Epi-fluorescent microscope is used for fluorescence microscopy and transmitted field observation. It is equipped with no magnification heterochromatic aberration infinity plan achromatic fluorescent objectives and wide-field eyepieces have a clear picture and wide view field. The transmitted and epi-fluorescent illumination light sources are high power & brightness LED, but power consumption is lower and use life longer, very good radiating heat effect. Safely and comfortably using the instrument, the cost of use and maintenance are lower. It is the ideal instrument in biology, cytology, oncology, genetics, immunology, etc. It also can be used in scientific research, universities, medical treatment, epidemic prevention, etc.


1) Adopt an infinity optical system and modularization function design.
2) Equipped with infinity plan achromatic fluorescent objectives, enable obtain a clearer and brighter image.
3) Wide-field plan eyepieces: field number Ф22mm.
4) Coaxial coarse/fine focus system, with tension adjustable and limit stopper, minimum division of fine focusing: 2μm
5) Transmitted illumination: 3W high brightness white LED, brightness adjustable.
6) Epi-illumination: 3W high brightness monochromatic LED,  enable changing for different wavelength LED, but the brightness can't be adjustable.
7) Trinocular can be observed for eyepieces and microphotography in 100% light flux, suits for low illuminance microphotography.
8) Wide voltage range power supply (85-265V 50/60Hz).
