1064 nm Raman Lasers
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.
The 1064 nm Raman excitation wavelength generates minimal fluorescence. Although the Raman signal is much weaker (6% of what would be predicted for 532 nm), the near-absence of fluorescence permits spectra to be obtained with a reasonable signal to noise ratio.

Raman Sample Holders
Ocean Insight offers sample holders for Raman analysis of liquids and solids. The holders accommodate Raman probes from 9.5 mm-12.7 mm diameter, and 1 cm pathlength cuvettes and vials of various dimensions.
The RM-SERS-SHS holder is ideal for surface enhanced Raman spectroscopy (SERS) substrates, which comprise nanoparticle chemistries on slides. The holder accommodates standard glass SERS slides and connects to a Raman probe.
The RM-LQ-SHS holder accommodates vials and cuvettes. It has a magnetic cover, making it easy to load and unload samples, block ambient light, and improve the accuracy of Raman measurements.
Two other options are available: the OOA-RAMAN-SH sample holder for vial and cuvette measurements; and the multipurpose OOA-HOLDER-RFA for Raman, fluorescence, absorbance and reflection measurements.
