DLC/HEAR Coating for IR Optics

A DLC coating is the preferred choice for IR optics that have to withstand harsh environmental conditions. It adheres to virtually all lR substrates - Ge, Si, ZnSe, ZnS, CaF2, sapphire, and chalcogenides. It is an Anti-Reflective (AR) coating with high hardness and good stress resilience with minor losses (between 5-10%) in transmission.  Our proprietary "coat up" PE-CVD process virtually eliminates typical coating defects - pinholes, stress, uniformity and adhesion.  Coatings adhere to MIL-M-13508C and MIL-C-675C standards for adhesion, abrasion, humidity, solubility, salt spray, temperature cycle and sand-slurry wiper.
