ABSTRACT:
A radiation shield in a light detector and/or sensor assembly generally comprises a horizontally oriented buffer on which the detector is disposed, a vertically oriented radiation shield surrounding the detector, and a horizontally oriented collimating buffer disposed on the vertically oriented radiation shield above the detector. Advantages of the invention include minimization of the effect of radiation emitted from the hot junctions of a thermoelectric cooler employed in the detection assembly, and the provision of an electromagnetic shield when the arrangement is connected to the low-impedance side of the amplifying circuitry associated with the detector. The buffer preferably comprises a highly emissive material, while the collimating buffer is preferably of an electrically conductive material. Electromagnetic shielding can be provided by the use of high permeability material. Finally, the shield, buffer and collimating buffer may be insulated from the detector and thermoelectric cooling elements, and may be connected to a suitable point of amplifier circuitry associated with the assembly to minimize the effect of noise from the thermoelectric cooling device.
