Went up to the attic, Found the book but not John Carter's old GE catalogues in need of future looking for I believe 1970's date.
Part 198 - Mechnical and Acoustical Coordination; "Selective Control of Radiant Energy." P. 203 Architectural Lighting Graphics, John E. Flynn Van Nostrand, NY. 1962.
If you can find a copy of this book.... It is in my top ten of all books read.
Concept of "Interference Filters", with other notations on the concept.
- Interference Filters: These filters are sometimes called "Dichrolic" and provide selective transmission of radiant energy. They are generally used to transmit light and reflect the invisible radiation.' Infra-red in the beam is minimized (up to 85% reduction) with no sigificant loss of light. Re-directed radiant energy is diflected to a heat-absorbing collecting surface which must be cooled by more conventional air or water techniques.
A constant joke with Mark from Osram I play, is water cooled halogen lamp invention given some xenon lamps have them. This might be the source of the joke, but also shows that dichroic technology started years before I was born.
