    摘要： An emitting source capable of radiating substantial energy in the near infrared spectrum and suitable for use in non-dispersive infrared gas analyzers or other devices is described. Operation can be steady state (DC) or pulsed at high frequency with excellent modulation characteristics. The device consists of a tungsten filament mounted across the pins of a small transistor outline header and centered at the focal point of a parabolic or other shaped reflector. The header assembly is enclosed by a resistance-welded cap and window assembly having a specially sealed sapphire or other suitable IR transmissive window. Fundamental to the operation of the inventive IR emitter is the incorporation of a getter within the header package configured to prevent oxidation degradation of the tungsten filament. An inert gas backfill limits filament evaporation and further extends apparatus lifetime.

    摘要： The present invention has a lamp/getter assembly which reduces or eliminates mechanical and chemical wearing of the filament/leads in a lamp. One or more getters are formed across the filaments of the lead wires of a lamp during construction. During the cooking and sealing off process, the mechanical integrity of the lead wire/filament geometry is maintained by the effect of the getter structure. After the sealing process, the lamp is operated at lower than operating voltage and the getters operate to remove impurities. When the lamp is then operated at normal voltage and temperature, the getter melts and breaks.

    摘要： A tungsten halogen lamp which utilizes a quantity, in combination, of an organic getter and inorganic getter for the purposes of substantially eliminating contaminants contained within the lamp and substantially reducing filament sag. In particular, the organic getter may be in the form of a carbon-containing halide, such as methyl bromide, and the inorganic getter may be in the form of a phosphorus-based gaseous getter, such as phosphine.
