561 nm Yellow-Green DPSS Lasers

561 nm yellow-green DPSS lasers are specifically engineered for live-cell imaging and confocal microscopy. Unlike 532 nm lasers which can cause phototoxicity and bleed-through, 561 nm matches the peak absorption of red fluorescent proteins including mCherry, RFP, Texas Red, Alexa Fluor 568, and tdTomato with minimal background autofluorescence.

Key applications

  • Confocal fluorescence microscopy (mCherry, RFP, Alexa 568)
  • Live-cell imaging with reduced phototoxicity
  • TIRF (Total Internal Reflection Fluorescence) microscopy
  • Super-resolution microscopy (STED, PALM, STORM)
  • Flow cytometry red-fluorophore excitation
