5795 DE GASPE AVENUE, #222 MONTREAL, QUEBEC, H2S 2X3 CANADA LLTF CONTRAST™THE ULTIMATE SUPERCONTINUUM FILTER The Laser Line Tunable Filter is a non-dispersive tunable bandpass filter based on volume Bragg gratings. It combines very high optical density (> OD6), an outstanding out-of-band rejection, and wide tunability. The LLTF can be customized to cover the entire 4002500 nm spectral range in a single instrument with a high spectral resolution. It can be coupled with a wide variety of broadband sources to create a tunable laser source. It can also be used as a cleanup filter for spectroscopy applications.
