300-860nm long wave pass linear gradient filter

The long-wavelength linear gradient filter adopts a continuous coating method and is based on a multi-layer wedge-shaped film structure to achieve spatially continuously changing filter characteristics. The film slope can be adjusted according to the dispersion requirements to achieve the target linear rate of change. Linear gradient filters have highly integrated spectroscopic capabilities and have irreplaceable advantages in the miniaturization and lightweight design of spectroscopic instruments. Products are widely used in lightweight hyperspectral imaging spectrometers, portable spectrometers, and medical endoscopes.
