摘要：It is a problem of pyrometric temperature measuring of melts in a vacuum thatthe material of the melt will be deposited on mirrors, windows and other optical devicesso that the radiation will be screened more and more effectively, the closer it comes tothe pyrometer. In order to avoid vapor desposition in the path of radiation, a gratingarrangement is provided between the melt and the pyrometer, which focusses theincoming radiation and concentrates it onto the pyrometer. The grating arrangement ispartly permeable to the molecules of the melt material. The direct path between themelt and the pyrometer is blocked by a screen. In this way, vapor deposition on thewindow prefixed to the pyrometer are avoided, while the radiation can reach thepyrometer.
