Fluorescence microscope MF31
Entry-level upright fluorescence microscope MF31

MF31 series fluorescence microscope adopting excellent quality infinity optical system combined with LED fluorescence illuminator. The LED fluorescence system is modular design, does not need external power box, it can offer blue, green and UV fluorescence excitation groups. Digital screen shows and remember each fluorescence channel light intensity. The microscope is good for entry level fluorescence observation such as immunofluorescence and bio-fluorescence, and bright field of biological slide. It is easy to operate, environment protect and high safety, widely used at school, university lab, medical center and science research institute. Users can chose different models based on fluorescence channels.


  • Microscope works for bright field and fluorescence.

  • 100% light division for view in eyepiece and camera imaging.

  • Eyepiece has 22mm wide field of view and high eyepoint.

  • Excitation wavelength covers 330nm~580nm.

  • Configuration is available of three different fluorescence channels.

  • Each group of fluorescence cube is lighted by 3W LED lamp.

  • Slide holder can hold double pieces slides at one time.

  • Instant ON/OFF without preheating or cooling.

  • No requirement of external power box or lamp box.

  • Flexible expanding functions to polarization, white LED epi-illluminating and heating.
