  11. 638 nm Raman Lasers

638 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.

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.

Spares and accessories for 638 nm Raman Lasers

Raman Laser Safety Glasses

Raman laser safety glasses offer great protection from laser light without sacrificing visibility or comfort. The glasses are designed for both direct and diffuse viewing, are EN207-compliant and CE-certified, and are made using absorptive dyes that maximize color recognition and visible light transmission (VLT). Options are available for use with Raman laser excitation wavelengths including 532 nm, 638 nm, 785 nm, 808 nm and 1064 nm.

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.
