This infrared source is a thermal emitter with an emissivity of ~80%. It is appropriate for use in laboratory or field instrumentation due to its long life and stable properties.
The IR-43 radiating element is an approximately 1.5 micron thin film of precision laser trimmed resistance material which is permanently bonded to a flat substrate of alumina. This contributes to a uniform radiating source and a stable platform. The thin film design results in a low mass of radiation material. The use of this radiating elements is suited for particular applications that do not required high temperature (up to 600 °C).
The stable performance of IR-43 makes it one of the best sellers. The unit is free standing on a TO-5 header. Without a directly connected mass to draw of heat, it is very responsive. The unit does not require operation in a sealed atmosphere. IR-43 operates at 600°C with 1.3 watts input.
Parabolic (collimation, P-05) and elliptical (focusing, E-05) reflectors are available for the IR-43K.
