Abstract
A chemical vapor deposition process has been used to replicate shapes, patterns or highly reflective surfaces in infrared transmissive optical materials (ZnS, ZnSe) and mirror materials (Si, SiC) for a variety of applications, such as ZnS domes or meniscus lenses, ZnSe lens arrays for adaptive optics and low f-number Si/SiC mirrors for space optics. Conditions for achieving a high degree of replication are specified and replication results on several different substrate materials are presented. Techniques to obtain replication on those substrates which either are attacked in the CVD environment or whose thermal expansion coefficients are considerably different from that of the deposit are also discussed.
