Abstract

DLC coating by a high transmittance in the infrared region is applied to the IR Optical System window. In order to apply to the window, durability is needed. Depending on the surrounding environment, the coating can come off. In particular, ambient temperature, humidity, may occur because of chemical contamination. If you encounter a problem, the product is not reliable. Existing environment test is insufficient to assess the durability of DLC coating. We have devised an enhanced environment tests, test results could be evaluated DLC coating durability.
