Multispectral filter
7 month ago
The multispectral filter is precisely produced by the composite process of photolithography + coating. The deposition mask is produced by the high-precision reproduction photolithography technology, and the high-performance filter film of each spectrum segment is successively plated within the deposition pattern. Multi-spectral filters have high transmittance and excellent filtering characteristics. Multiple filter channels are integrated into a single substrate, and the spatial alignment accuracy is extremely high.
Application: Used in space multispectral imaging, multispectral imaging spectrometer, medical multispectral imaging.
