Home / Custom / Optical Components / Optical Filter / Pixel-Level (Mosaic) Multi-Channel Filter 
Pixel-level (mosaic) multi-channel filters feature multiple spectral channel units, with a significantly greater number of channels than RGB filters, thereby capturing richer spectral information, which can greatly optimize the structure of the imaging spectrometer spectrometer system. When it is used as a spectral component in the imaging spectrometer, it can realize the miniaturization and lightweight of the imaging spectrometer.
Spectral range(nm) | Single-channel dimension (μm) | Number of spectral channels | Channel half-height width(nm) | Filter size (mm) | Out-of-band cutoff frequency(%) | Peak transmittance (%) |
