✦ Synopsis

Microcalorimeters are special devices used for effective efficiency measurements of bolometric power sensors. The performance of the microcalorimeters, such as their sensitivity and accuracy, is mainly dependent on the thermoelectric detector. It can be improved by using thin-film thermopiles (copper-constantan or nickel-chrome) as an alternative to the traditional thermopile with bulky junctions. A thin-film thermopile specially designed for a microcalorimeter is described and experimental results are reported.
