The 80007 is a silicon carbide infrared source. The emission is a smooth continuum from 1.7 to 28 µm. Output is a 1.5-inch (38 mm) diameter collimated beam (1° divergence, full angle). The 80007 does not include an output window; it has a clear aperture, with a 1.5-Inch Series female flange. The system includes a SiC element (Infrared Elements for Light Sources in a housing with collimating mirror, and a stand-alone power supply.

Complete Source
The 80007 includes the SiC element in a housing with collimating mirror, and a stand-alone power supply. We used a parabolic reflector, rather than a condensing lens, as infrared refractive optics are very expensive and have transmittance limitations. A 3.3 ft. (1 m) long cable connects to the power supply. The power supply operates the element at ~2.4 A, 12 V.
Silicon Carbide Element
The element is a 3.8 x 12.7 mm, 24 W SiC glower; actual radiating area is approximately 3.8 x 5 mm.

Oriel® Lamp Housing is designed to operate in a typical laboratory environment (typically 68 to 76 degrees F, up to 45% relative humidity). Temperature and humidity outside of typical laboratory range can contribute to cooling and ignition faults. Cooling issues will cause the over temperature sensor to open, and ignition problems will result from high humidity. Contact a Newport Technical Representative for more information if operating outside the suggested range.
