The OD8-RLP633-B Raman Edge Filter is designed for 632.8 nm laser line suppression in Raman spectroscopy, providing OD ≥ 6 blocking over the 513-633 nm range and ≤ 3.2 nm edge steepness. It transmits > 90% of Raman-shifted light from 640.8 nm to 1400 nm with an average transmission ≥ 93%. The filter is housed in a 25.0 mm diameter ring with 2.0 mm substrate thickness, made of fused silica, and maintains 0° angle of incidence with random polarization. A scratch-dig rating of 60-40 applies over the 21 mm clear aperture, and an orientation arrow indicates light propagation direction.
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.
