Pulsable IR emitters suitable for fit and forget applications

Fitted with a tungsten filament providing mid IR radiation to over 5µ, LASER COMPONENTS has introduced pulsable infrared emitters to its EP range. The device comes in a standard TO8 package and has an expected lifetime of three years which is suitable for fit and forget applications such as gas sensing. The tungsten filament achieves the highest temperature and power of any material and is therefore a cost-effective source of near infrared radiation.

Glass and quartz glass envelopes are most commonly used in incandescent light bulbs but do not transmit well in the infrared, sapphire is a much better choice. The EP emitter has a patented design that integrates a sapphire window with a tungsten filament in a sealed metallic package, providing a robust source for spectroscopic instruments.

Tungsten filaments are provided in a variety of sizes to accommodate various frequency and modulation requirements. Operating temperatures up to 1,900K are standard with the EP source, all the devices include a gold plated parabolic reflector and an inert gas backfill.
