488 nm Cyan / Blue Lasers

488 nm is the primary excitation standard for life sciences, replacing legacy Argon-ion gas lasers with solid-state reliability and low power consumption. It is tuned to the absorption peak of Green Fluorescent Protein (GFP), FITC, Alexa Fluor 488, and DNA sequencing dyes. Available in compact direct-diode, low-noise DPSS, and single-frequency SLM configurations with free-space or single-mode fiber output.
