Diamond-Like Carbon (DLC) Coatings
This is an extremely rugged and abrasion resistant anti reflection coating, making it ideal for external surface applications where extreme environmental conditions will be encountered such as marine environments. Umicore can successfully apply DLC coatings to Germanium and Silicon substrates.
Below is a table showing the typical specification of Umicore’s DLC coatings.
