Transparent Heat-Mirror Materials and Deposition Technology

This work consists of selected papers on architectural coatings from two seminars held by the International Society for Optical Engineering (SPIE) January 25-29, 1982 in Los Angeles, Calif. The papers were selected from Optical Coatings for Energy Efficiency and Solar Application Vol. 324, edited by C.M. Lampert and Optical Thin Films Vol. 325, edited by R.I. Seddon. All papers are reproduced by permission of the authors and SPIE. Full proceedings can be purchased from SPIE, PO Box 10, Bellingham, WA 98227-0010 USA.

This collected work represents a sampling of the research and development interest in transparent heat mirror films for mainly architectural uses. The heat-mirror coatings discussed range from single-layer semiconductors to dielectric/metal/dielectric multilayers. New ternary compounds and nitride films are also introduced. Properties of heat mirrors deposited on glass and polyester substrates are discussed. The final section deals with large-scale processing, which is the link between research and development and mass production. Details of large physical vapor deposition, chemical-vapor deposition, and roll-coating systems are presented.
