Trends in CVD Optical Applications

The following is a listing of recent optical applications, either present or potential, where CVD may play a maj or role. 

The major optical coating process remains evaporation. However, sputtering, solgel, and CVD are making inroads because of the better properties they provide.fi l At this time, it is not clear which coating process will prove best but CVD, because of the excellent bond and hardness of the deposited materials and the relatively moderate cost of the equipment, is a good candidate.
