IR Source IR-18 & IR-19


 The IR-18/19 Series is designed for those customers who require higher temperatures and greater output from their infrared source. These emitters are manufactured using a patented silicon nitride material. The advanced ceramic technology ensures a very stable product. Their robust design ensures intrinsic physical and thermal strength. When operated at 12 volts/18 watts the IR-18/19 reaches 1150°C.

 The IR-18 emitters are mounted in a 1 inch parabolic reflector for extremely efficient collimation of energy. The IR-19 emitters are mounted in a 1 inch elliptical reflector with an external focal point that is 1/2 inch in front of the clear aperture.
