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.
The following resources provide additional information on the infrared sources.

Electrically modulated IR sources
We have four types of electrically modulatable IR thermal sources. These are
Filament Sources from Helioworks:
CW and pulseable sources in TO-8 packages:

Diamond-like films from HawkEye:
The IR-5x series can be modulated electronically to 100 Hz. Details HERE.
Metallic 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.
Gas analysis is the usual application of these devices.
Silicon-based photonic crystal sources from ICx
These are silicon MEMS devices whose emissivity has been modified by surface structure control so that they emit selectively in the spectral region of interest. Currently available are devices with emission surpressed except in the 3-5 or 8-14 micron ranges. The result is improved 'wall plug' efficiency compared to gray-body emitters like most of the souces we offer. Click here for details on these devices, called TunIR restricted band IR sources.
