Varispec™ Liquid Crystal Tunable Filter

The VariSpec™ Liquid Crystal Tunable Filter (LCTF) is like a high-quality interference filter, but the wavelengths of the light it transmits are electronically controllable, providing rapid, vibrationless selection of any wavelength in the visible and near-infrared tuning ranges.

The VariSpec filter's unlimited wavelength selection and excellent image quality are particularly valuable in a wide variety of applications such as remote sensing, airborne hyperspectral imaging, Raman chemical imaging, and process quality control. Many national labs and universities have purchased these devices for general purpose spectral imaging research.

Channel Systems can assist with professional system integration including cameras, optics, mechanics and software.
