Optical laser-line filters for 405 nm for laser-based spectroscopy have narrow bandwidth of ~2 nm (FWHM), high transmittance, steep roll-off, and wide blocking of 300 to 1200 nm. Long-pass filters provide a steep edge, high transmittance, and low ripple in the passband in addition to deep blocking (>OD6) at 405 nm.

Iridian Now Offers Filters at 405 nm
Ottawa, Canada - Iridian, the leader in optical filter solutions, has added 405 nm filters to its line of market-leading optical filters for laser-based spectroscopy. An enabling technology for BluRay, 405nm laser diodes are becoming increasingly popular in many application areas, such as machine vision, high resolution printing, metrology, fluorescence, and spectroscopy. Iridian has introduced a 405 nm laser line and long pass filter, allowing the user to see more signal with less background in these applications.
Iridian's new 405 nm laser line filter offers a narrow bandwidth (~2 nm FWHM), high transmittance, steep roll-off and wide blocking (300-1200nm). This reduces spectral noise without compromising transmittance at 405 nm. The user can view Raman modes, fluorescence or desired signal while blocking the laser line with Iridian's new 405 nm long pass filter (LPF). Our LPF offers a steep edge, high transmittance and low ripple in the passband in addition to deep blocking (> OD6) at 405 nm.
Iridian Spectral Technologies Ltd (Iridian) - Ottawa, ON, Canada - Iridian is a diversified optical filter manufacturer that is an international leader in filter design and manufacture especially for application in the fields of fiber optic communications, optical spectroscopy, 3D entertainment, and in aerospace. Iridian was ranked as one of the top 150 high technology companies in Canada in the 2011 and 2012 Branham300 rankings and won the 2010 Canada Export Achievement Award for the province of Ontario sponsored by Profit magazine together with Export Development Corporation (EDC). Iridian is a global supplier with distributors in many countries particularly in Asia.
