400-1000nm linear gradient filter

Linear gradient filters employ a continuous coating process and rely on a multi-layer wedge-shaped thin-film structure to achieve spatially continuous variation in optical filtering characteristics. By adjusting the slope of the thin film according to dispersion requirements, it is possible to obtain the desired linear variation rate. Linear gradient filters boast highly integrated spectral separation capabilities, making them indispensable in the miniaturization and lightweight design of spectroscopic instruments. These products are widely used in lightweight hyperspectral imaging spectrometers, portable spectrometers, and medical endoscopes.
