Tunable laser line filters from Photon etc. Inc. remove unwanted plasma lines and fluorescence from laser sources over the full spectral range with high pointing stability and signal throughput. Based on volume Bragg gratings, the nondispersive slitless technology has a high damage threshold and can be combined with broadband sources, including supercontinuum lasers. The bandpass filters exhibit narrow bandwidth and high efficiency for all polarization states. Their specifications include bandwidth of <10 cm–1 (0.3 nm at 514 nm), an available spectral range from 350 nm to 2.5 μm, a tuning range up to 300 nm and peak transmission at center wavelength of >50%. Computer control is through a USB interface.
