Mosaic filter has a highly integrated spectrophotometric function, 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.
Optical glass such as K9, fused silica, sapphire, MgF2, silicon (Si), ZnSe, ZnS, etc. These materials possess high transmittance, low absorption, low scattering, uniform refractive index, and specific dispersion characteristics.
Precisely hemispherical. The machining precision of the center and radius of curvature of the sphere is extremely high.
The surface is precision polished to an optical grade of 10-5 to ensure image quality and reduce scattering and aberrations.
An AR coating is typically applied to the concave surface to maximize the transmittance of specific wavelengths of light (e.g. visible light) and reduce reflection loss.
