ABSTRACT:
A nondispersive infrared radiation source includes a base, a plurality of formed pins, a thick film resistor and an o-ring, the base has the shape of a cylinder and a plurality of grooves formed therein. A bore is formed in the base which is terminated by a bottom surface defined by a spherical radius. A reflective coating is applied upon the bottom surface. The plurality of formed pins are heat staked into the plurality of grooves and the o-ring is placed in one of the grooves. The thick film resistor comprises a substrate, a dielectric glass layer and a conductor layer, the substrate has a plurality of thick film resistors which are formed thereon. The plurality of thick film resistors are separated by use of a quadrapole laser. The thick film resistor is electrically connected to the plurality of pins with a solder connection. A DC source is electrically connected to the plurality of formed pins, and infrared light radiates from the resistive pad striking the reflective surface in the base, and the infrared light emits from the second end of the base.
