An optical coating manufacturer sells either a coating service on parts you supply or a finished coated component; the two split risk differently. Coating-only supply leaves substrate identity, surface condition and scrap replacement with the buyer. A coating design belongs to one substrate index: the…

Choosing a bandpass filter manufacturer involves more than selecting a filter with the right center wavelength. In a real optical system, the finished filter may also need to meet requirements for bandwidth, transmission, blocking, optical density, angle of incidence, beam geometry, polarization, substrate, dimensions and…
