Bandpass Linear Gradient Filter
The Linear Gradient Filter has the ability of high integration, and has the irreplaceable advantage in the miniaturization and lightweight design of spectral instrument.
linear gradient filter using continuous coating method, based on multi-layer wedge-shaped film structure to achieve spatial continuous changes in the filter characteristics. The slope of the film can be adjusted according to the dispersion demand to obtain the target linear rate of change.
