Developed as a versatile excitation light source for FLIM in the frequency domain our Multi-LED system includes up to 4 LEDs, each providing excitation light at high modulation depths. Compared to other light sources, LEDs provide non-phototoxic illumination levels, have a low cost and a long economic lifespan. Available wavelengths cover the range from 360 to 640nm.

The Multi-LED is part of our LIFA and LIFA-X products for FLIM?/ FRET, and is also seamlessly integrated with the LI-FLIM software. For each LED automatic control is available for LED selection, LED current and modulation frequency. Temperature stabilization of the LED is optionally available to avoid a lifetime drift during time lapses.
