532nm DPSS lasers can vary in wavelength by +/-0.5nm or much more. Iridian 532nm ultrasteep LPFs are designed to operate at 0 degrees AOI and with a laser wavelength of 532.0nm. A variation of +0.5nm in wavelength can decrease the blocking to OD4; +1nm can decrease the blocking to OD1. Iridian ultrasteep LPF filters must be paired with very precisely known laser wavelengths to realize high OD and low cutoff. Iridian produces laser line edge pass filters for users who have larger uncertainty in AOI and wavelength, please inquire for more details.
