Thin Film Coating |
RPO’s production coaters and spectrophotometers for coating metrology allow us to provide standard and custom coatings, offering greater performance for reflective and transmissive requirements. From standard MgF2 AR’s and Multi- Infrared Broadband AR Coatings RPO also offers optics including robust infrared antireflective (AR) coatings used in thermal imaging and sensing applications. These coatings use no radioactive materials, are designed to moderate abrasion requirements, and exhibit high transmission in the long wave infrared region. The coating design can be modified to meet transmission or reflection requirements in the 7 to 14 micron wavelength range. Use of ion beam assist during thin film deposition achieves a relatively low stress, adherent, high-
Infrared Broadband and DLC AR Coatings for Durability For harsh environmental applications, a diamondlike carbon (DLC) coating on the exterior surface of the germanium, coupled with a high efficiency AR coating on the opposite side provides both protection and the highest transmission available. The DLC coating meets not only severe abrasion test requirements, but also various wiper, sand, sun and rain tests. These infrared optical coatings have been qualified for military platforms on the ground, in the air, and at sea.
