| An optical pyrometer measures the blackbody temperature by sensing radiation from one end of the furnace. The initial operation has demonstrated long-term stability of the blackbody temperature within these limits. Because the former angle is larger than the latter one, geometrical optics suggests that the total power detected depends only on the blackbody temperature and a geometrical factor related to the pinhole aperture, detector optics, and relative separation, because the detector pupil is overfilled. |
