It uses a constantan-Manganin thermophile consisting of 100 junctions imprinted on an alumina ceramic substrate in a circular pattern to minimise azimuthal sensitivity. 3M Velvet Black is used on the receiver surfaces. It has two concentric hemispherical domes ground from Schott K5 glass. The transmittance spectra of the K5 exhibits a cut-on limit at 310 nm in the ultraviolet and a cut-off limit at the 2800 nm. The compensation element is a second alumina substrate that along with the compensation circuit prevents temperature-induced instrument zeros."@en ; skos:inScheme ; skos:notation "SDN:L22::TOOL0921" ; skos:note "accepted"@en ; skos:prefLabel "Kipp and Zonen CM10 pyranometer"@en ; skos:related . skos:narrower . skos:related . skos:narrower .
