Thermal Sources

Miniature, CW 1100K and 1275K IR blackbody sources

Our standard wirewound filament sources have an emissivity of ~0.8 and are available in 4-watt, 8-watt, and 13-watt versions. The coil is wound on an alumina ceramic cylinder. Operation in a controlled or sealed atmosphere is not required.  The 1100K 8-watt version is also available in a mechanically identical 1325K version drawing about 13 watts.

Electrically modulated IR sources

We have four types of electrically modulatable IR thermal sources.  These are

1. Tungsten filament sources from Helioworks
2. Diamond-like film sources from HawkEye
3. Metalic foil sources from ICx (formerly Ion Optics)
4. Silicon-based photonic crystal sources from ICx.

Metalic foil sources from ICx:

Electrically modulated IR sources in TO-5 and TO-8 packages.   In general, these devices are useful with pyroelectric and thermopile detectors optimized at frequencies < 10 Hz.

• PulsIR Pulsed Infrared Radiator
• ReflectIR Collimated Pulsed Infrared Radiator

Gas analysis is the usual application of these devices.

• PulsIR Evaluation Kit Driver
• PulsIR Note on Appropriate Use

Mechanically modulated IR sources

We also offer hybridized versions of our CW IR sources with mechanical modulation (choppers) from <1 Hz to >1000 Hz.

• CH-10S and CH-20S modulated IR sources

We also offer hybridized versions of our optical shutters with IR sources.

• CH-50S and CH-60S modulated IR sources
