Detailed introduction

A optical filter is an optical component that selectively allows or blocks light of different wavelengths.They are typically made of a special material that can absorb or reflect light of a specific wavelength while allowing other wavelengths to pass through.Filters are widely used in various optical instruments,such as cameras,microscopes,spectrometers,and lasers.Zhonghong Technology can provide a variety of filters,such as broadband,long-pass,and band-pass filters,made of materials such as silicon,germanium,sapphire,fluoride,and zinc selenide,with different shapes and parameters.We also accept customization according to your requirements.
