Epi-LED FL Fluorescence Illuminator




The innovative LED-based fluorescence
  • Economical LED concept is a much better solution for fluorescence excitation than traditional mercury or metal-halide lamp.
  • With an incredibly long lifespan of 10,000 hours, LEDs offer unrivaled durability, user-friendly operation experience, and safety for most of the applications.
  • No need to re-align the light source.
  • Convenient intensity adjustment.
Rapid switching
  • Simple switching between “FL” and “BF” allows BA310 Epi-LED FL to employ brightfield transmitted light techniques or fluorescence reflected light techniques freely according to requirements.
  • The versatility of BA310 Epi-LED FL in its fluorescence application is unrivaled. Its applications include tuberculosis inspection and conventional pathological investigation.
Auto ON/OFF mode
  • Under intelligent auto ON/OFF mode, the illumination light turns off automatically when the user leaves the microscope, and switches on when the user returns to the front of the instrument.
  • This function prevents slides from long time exposure from fluorescence excitation.

Versatility with replaceable LED module and filter cube for different applications*


The modular LED module can be easily changed according to the staining dye. BA310 Epi-LED FL is not only suited for TB inspection, but also other infectious diseases such as malaria and insomnia. Additionally, it is suitable for simple laboratory and routine application for fluorescence excitation such as FITC, DAPI staining.


* It is recommended that replacement of LED module should only be done by Motic authorized trained personnel.
