摘要: An apparatus for measuring the temperature of an object placed in a plasma by utilizing radiation includes measuring means for measuring the intensity of radiation from the object and the intensity of plasma light in different directions at the same time. The measuring means includes a first lens for receiving the radiation from the object and the plasma light, a second lens for converting the output beam of the first lens into parallel light rays, a third lens for focusing the parallel light rays, and an interference filter disposed rotatably between the second lens and the third lens.
