The laser line tunable filter (LLTF) is a non-dispersive tunable bandpass filter based on volume holographic gratings. It delivers the highest signal throughput in the industry and is also unique in that it combines very high optical density (> od6) and outstanding out-of-band rejection with wide tunability. more...
