Photolithographic multispectral filter of 5 channels

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. Standard product： Standard product： Central wavelength（nm） · Half peak bandwidth （nm） Gradient（nm） · Block deth Average transmittanc（%） 485±10 9…
