THIN LAYERS IN OPTICS (TENKE VRSTVY V OPTICE),
FOREIGN TECHNOLOGY DIV WRIGHT-PATTERSON AFB OH
Pagination or Media Count:
A survey of problematics is given which are presented today by thin layers with respect to their optic applications and to their inherent production, especially with regard to the portion of vacuum technology for this production. Interferential layers in optics came into practical application around 1935. The possibilities which thin-layer optics give the optical designers are described by the names of typical systems anti-reflection layers, opaque mirrors, monochromatic filters of the narrow and wide zone type, blocking filters of the high- and low-pass filter type in the function of heat filters, cold mirrors, dichroitic mirrors, etc., phasing layers, interference polarizers, layers which increase the reflectivity and durability of metal mirrors, color correcting systems, jewel effects, etc. It is necessary to realize the kind of work which is hidden by these productions. The task of technology is to achieve the given composition. This depends on what conditions production will function and in what series they will be produced. The group of physical and technological properties which are summarized lead to the vacuum atomization of stable and durable layers with required optical constants.
