The OD8-RLP633-B Raman Edge Filter is specified for the 633 nm laser line for Raman applications. The filter is manufactured to provide ≥ OD6 laser line rejection and steep transition of 1% to Tabs ≥ 90% and ≥ 93% average over the 640.8 nm to 1400 nm transmission range. These filters enable the detection of low-wavenumber Raman signals with exceptional sensitivity and a high signal-to-noise ratio. They support applications including Raman spectroscopy, portable Raman analyzers, and industrial Raman probes, providing versatile solutions for both laboratory and field use.
