Description
The TS-76 is a combination of a thin-film thermopile (76 thermocouples) with a meandering thin-film heating element and a thermally equalising Ag layer, whereby all layers are electrically insulated from each other. Although all elements of an electrically calibrated or electrically substituted radiometer are included, the TS-76 is generally not used as an absolute radiometer, but as a secondary or transfer standard. The absorbing layer is made of Ag black and shows a very high broadband absorption in the infrared range. The thin-film thermopile is manufactured from highly efficient bismuth and antimony layers using microlithographic processes. The sensor with a receiving surface of 7 mm diameter is supported on a thin silicon nitride membrane. The dimensions of the Si chip are 12.5 mm x 12.5 mm. The chip is generally mounted on a base and placed in a special metal housing filled with Xe gas. The entry window is wedge-shaped with an angle of about 1.5°.
