Diamond-like (DLC) optical coatings are optical protective coatings for the infrared range.
Currently, optical diamond-like coatings are applied to germanium and silicon substrates with a maximum size of 300x400 mm with guaranteed coating uniformity of ±3%. Diamond-like coatings combine high mechanical strength and high transmittance.
I-Photonics offers manufacturing of bandpass and cut-off filters according to the Customer's specification in the range from 260 to 5 000 nm.
Interference optical filters are a piece of optical glass (or other optical material) with an optical coating.
