Home / Custom / Optical Components / Optical Filter / Pixel-Level (Stepwise Gradient) Multi-Channel Filter 
Pixel-level (stepwise gradient) multi-channel filters employ a continuous coating process and rely on a multilayer wedge-shaped thin-film structure to achieve spatially continuous variations in optical filtering characteristics. Pixel-level (stepwise gradient) multi-channel filters boast highly integrated spectral separation capabilities, offering irreplaceable advantages in the miniaturization and lightweight design of spectroscopic instruments.
