Multi-LASER

Light Source for Frequency-Domain FLIM

 

The Multi-LASER is a light source for frequency-domain fluorescence lifetime imaging microscopy. The Multi-LASER contains up to 6 laser diodes with different wavelengths.

The Multi-LASER modulated diodes offer the high stability and high modulation depth required for lifetime imaging, and can also be used for regular fluorescence imaging. Using the Kineflex coupling system the light source can be easily coupled into your microscope stand for multi-beam confocal illumination, TIRF illumination, and widefield illumination. The Multi-LASER is part of our LIFA product line for fluorescence lifetime imaging microscopy. For each laser line the laser power and modulation characteristics can be set from the LIFA software LI-FLIM.

Applications

  • Fluorescence imaging
  • Flow cytometry
  • LED inspection
  • Crude oil characterization
  • Machine Vision
     

Models

Two models of the Multi-LASER are available: a standard version including up to 6 lines with a 50 ps lifetime repeatability for 0-4 ns lifetimes, and an extreme version with a ultra-high modulation depth including up to 4 lines with a 20-30 ps lifetime repeatability in the same lifetime range.
