Ocean Insight offers high power lasers for Raman excitation wavelengths of 532, 638, 785 and 1064 nm. These multimode diode lasers produce narrow spectral lines, have integrated laser drivers, and are thermoelectrically cooled for optimum performance.

Raman spectroscopy at 638 nm excitation effectively balances signal level with fluorescence and offers very good resolution. Also, 638 nm is a versatile wavelength for generating high-quality SERS data for a wide range of analytes.


  • Integrated laser package – turnkey solution with integrated laser drive, TEC cooled electronics and safety switches
  • Multiple options – available in 532, 638, 785 nm and 1064 nm Raman excitation wavelengths
  • 638 nm Raman excitation -- balances signal level with fluorescence; useful for biomedical applications 
  • Adjustable output power – options for manual or remote control of laser drive current
