Upright Fluorescence Microscope, LW300LFT

Instrument use:

 LW300LFT epi-fluorescence microscope is suitable for fluorescence microscopy and transmission bright field observation. Using infinity flat field achromatic objective lens and large field of view eyepiece, the optical system has clear imaging and broad field of view. It is biology, cytology, oncology, genetics. The ideal instrument for research work such as immunology, which can be used by scientific research, universities, medical and epidemic prevention departments. The LW300LFT trinocular epi-fluorescence microscope can be equipped with an adapter lens to connect with a camera or a digital camera to facilitate image editing, printing, and saving.

Performance characteristics

1. Designed with infinity optical system and modular function.

2. Configure high-quality infinity flat-field achromatic fluorescent objectives for clearer and brighter images.

3. Wide-angle flat field eyepiece: field of view diameter Ф 22mm.

4. The coarse micro-motion coaxial focusing mechanism, with locking, limit device, micro-motion value: 2μm.

5. Transmission lighting system: built-in field diaphragm, 6V30W halogen lighting, add heat sink, brightness adjustable.

6. Epi-illumination system: 100W / DC high-pressure mercury lamp, power box 220V / 110V optional.

7. The trinocular tube can be freely switched between visual observation and photomicrography. It can be 100% light when shooting, suitable for low illumination microscopic image shooting.
