IR Source IR-40 Series

IR-40NC Features

 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.

 These thin film units operate at ~600°C when powered with 4 watts for the IR-40 or 1.2 watts for the IR-43. The radiating element is an approximately 1.5 micron thin film of precision laser trimmed resistance material. The IR-40 element is permanently bonded to a flat substrate of alumina forming a stable platform. This contributes to a uniform radiating source. The unit does not require operation in a sealed atmosphere. The thin film design results in a low mass of radiation material.

IR-40 The IR-40 unit is attached to a TO-5 header with high temperature cement. This unit is also offered without a cap (as an IR-40NC) and with a cap and sapphire window (as an IR-40S).

 The IR-43 unit is free standing on a TO-5 header. It requires less power to achieve the same temperature as the IR-40. Without a directly connected mass to draw of heat, it is more responsive.
