Abstract
889,398. Semi-conductor devices. FAIRWEATHER, H. G. C. (Barnes Engineering Co.). March 17, 1960, No. 9452/60. Drawings to Specification. Class 37. A bolometer consists of a flat thermister flake of thickness not greater than 30Á mounted on a backing block of high thermal conductivity and having a thin very uniform layer of plastic of low heat conductivity between the flake and the backing block. Polyethylene terephthalate of thickness 50Á or less is the preferred plastic and the cement between the flake and the plastic and the plastic and the backing block is very thin exposy resin. Quartz, sapphire, magnesium oxide, beryllium oxide and copper are mentioned as the backing materials. The flake is covered with a blackening material to assist heat absorption. The time constant of such a bolometer is determined by the thickness of the plastic and the cement layers are so thin as not to add substantially to the thickness of the plastic film. The construction described is said to produce a thermister bolometer with a single time constant over a wide range of frequencies.
