Infrared Source Series 4x

The HawkEye Technologies IR-40 Series thin film units operate at approximately 600° C when powered with 4.0 watts for the IR-40 and 1.3 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. 

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). For alternative mounting, it is also offered attached to a flat, butterfly shaped, steel header (as an IR-42).

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