Optical Applications of DLC

DLC is not as good an optical material as single crystal diamond but, as seen above, it has many advantages as a thin coating and is satisfactory in many applications. The following is a review of present and potential optical applications of DLC. [Pg.352]

DLC in infrared (IR) Optics. In Ch. 11, Sec. 6.2, it was shown that diamond is transparent in the infrared beyond 7 m. DLC, although not as transparent as diamond, is suitable and is used or considered for a number of IR applications.PlP l [Pg.352]

DLC coatings also have an opto-protective function, infrared window materials such as germanium, magnesium fluoride, cadmium telluride, zinc sulfide, and zinc selenide are rel h/ely soft and easily damaged and eroded by wind, rain, or particle impact. They have also poor resistance to corrosive environments. DLC coatings offer good protection with adequate optical properties. However, their narrow IR bandpass may limit the range of applications.
