IR reflectors
Emitters radiate in all directions, so reflectors are placed behind them to redirect as much of the radiation as possible onto the product in the desired manner. Appropriately placed reflectors can irradiate the whole product uniformly, or focus radiation on a section that needs extra heating. Reflector materials include ceramics, polished aluminum or stainless steel. Gold is often used in tubes and lamps with built-in reflectors. Dirt severely degrades all infrared performance and can lead to lamp overheating and premature failure, so external reflectors need to be cleaned. Internal reflectors are also available to eliminate this requirement. ir_reflektory.jpg

Reflectors come in several different forms. Quite often, they're separate panels mounted behind the emitters. However, one emitter design uses a twin bore tube with the filament in one bore and a thin layer of gold plated on the inside of the second bore. Thus, the reflector is an integral part of the emitter.

It may be necessary to cool reflectors, lamps, and wiring to prevent premature failure. Usually, air is blown over them (from behind to eliminate blowing dust). The hot air can be recycled to heat other parts of the work area, or to augment a convection oven if the Infrared unit is being used as a booster oven.
