638-nm Optical Filters
BioPhotonics
Nov 2013Iridian Spectral Technologies’ 638-nm optical filters for Raman spectroscopy allow users to observe the Raman signal while suppressing excitation and background sources.
The Raman edge pass filters provide >90% absolute transmittance and <±2% ripple for the Raman light. They also provide an ultrasteep edge with cutoff <50 cm–1 and optical density >6 blocking at 638 nm.
The 638-nm laser line filters offer a ~2-nm full width half maximum bandwidth, high transmittance, steep roll-off and blocking from 300 to 1200 nm.
