Supercontinuum Tunable Filters
Photon etc. ‘s LLTF Contrast™ is an advanced, non-dispersive tunable bandpass filter designed to convert a broadband supercontinuum laser into a high-precision, continuously flexible light source. Operating across a wide spectral range from 400 nm to 2500 nm (VIS-SWIR), this solution delivers exceptional out-of-band noise rejection (> OD6) alongside unmatched pointing stability. By combining high optical throughput with seamless wavelength selection, it provides researchers with an uncompromised tool for demanding applications like Raman spectroscopy, photoluminescence excitation, and optical calibration.
