Abstract
PURPOSE:To reduce a radiant ratio and to obtain a high S/N, by constituting a plane confronting with a main reflection mirror in a reflection mirror spider supporting structure of a material having a high reflectance in an infrared ray area. CONSTITUTION:The plane 6a' confronting with the main reflection mirror 2 of a spider 6 is constituted of the material having the high reflectance in the infrared ray area. The plane 6' is set as the grinding plane made of Al, and a ray outputted perpendicularly from the plane 6' confronting with the main reflection mirror 2 of the spider 6 is emitted to a room via the main reflection mirror 2. Since relation between the reflectance gamma and the radiant ratio epsilon is set as gamma+epsilon=1, it is possible to reduce the radiant ratio of noise infrared ray by increasing the reflectance gamma forming the plane 6' of the spider 6 with a mirror of Al. Thus, it results that an input signal to a measuring instrument = (the signal 8 of a celestial body to be measured) + (the noise infrared ray 10 emitted from the spider 6 with a low radiant ratio), then, the noise in the measuring instrument can be reduced.
