1100-1700nm image-level (tile-like) multi-channel filters

Image-level (tile-like) multi-channel filters are continuously coated and realize spatially varying filtering characteristics based on a multilayer wedge-shaped film structure. The pixel-level (tile-like) multi-channel filters have highly integrated spectral capability, which is an irreplaceable advantage in the miniaturization and lightweight design of spectral instruments. The products are widely used in lightweight hyperspectral imaging spectrometers, portable spectrometers, and medical endoscopes.
