use ultrasonic automatic cleaning machine to prepare the substrate, including removing oil, dust, finger prints, acid and alkali corrosion on the substrate surface, etc.
According to spectral requirements of customers, the film system design and feasibility evaluation are carried out through the software. Considering the feasibility of the manufacturing process, manufacturing tolerances, design sensitivity, yield, etc., the better design is given.
According to the coating requirements, the ion assisted coating technology IAD, APS, ion beam sputtering IBS, electron beam evaporation EB, and resistance evaporation and other processes are used to achieve the alternating growth of the film layer.

Spectrally qualified coated optical components also need to be manually inspected to screen out defective products such as splash ideas, scratches, corrosion, and scratches on the surface.
Abrasion and adhesion - performed per MIL-PRF-13830B and ISO Specifications.
Salt solubility and salt spray fog - performed per MIL-C-14806A and similar specifications.
Temperature/humidity chamber - environmental testing per MIL-C-675C and similar specifications.
Spherical surface figure accuracy (PV/RMS): measures surface apertures, local deformations, defects, mid-frequency/high-frequency errors of convex/concave spherical lenses, spherical mirrors, etc.; as well as plane figure (PV/RMS), flatness, and parallelism measurement.
