Request info

The Laser Line Tunable Filter (LLTF Contrast) is a non-dispersive tunable bandpass filter based on volume Bragg gratings. The LLTF Contrast combines very high optical density (> OD6) and outstanding out-of-band rejection with wide tunability. A single filter can be tuned from 400 nm to 1000 nm (VIS) or 1000 nm to 2300 nm (SWIR), with bandwidths (FWHM) of <2.5 nm and <5 nm respectively. Custom and extended spectral ranges (up to 2500 nm) and bandwidths (sub-nm) are also available. Photon etc’s LLTF Contrast can be coupled with a supercontinuum laser to provide a Tunable Laser Source.
