Optical filter refers to the coating of one or more layers of dielectric film or metal film on optical elements or independent substrates to change the characteristics of light wave transmission. Utilize the characteristic change phenomena of light waves in the transmission of these films, such as transmission, absorption, scattering, reflection, polarization, phase change, etc., and then design and manufacture various filter products to achieve scientific and engineering application purposes. Manufacturing optical glass filters technology is a complex engineering technology, involving many professional technical fields, including vacuum acquisition technology, vacuum measurement technology, computer-aided design technology, optical characteristic testing technology, electronic circuit technology, material characteristic testing and preparation Technology etc.

Zoolied all optical components are precision instruments, especially optical filters, and the surface is easily scratched. Improper cleaning and storage methods may damage the surface film of the filters(including IR filters, OD6 optical filters，UVC Filters etc.), reduce its application performance and shorten its service life. Therefore, the correct maintenance method is extremely important.
