Abstract

PURPOSE:To reduce the reflection of light in the near infrared wavelength range by providing a thin dielectiric film on the surface of a metallic reflecting material which lights a lighted body reflecting light from a light source in a copying machine, etc. CONSTITUTION:Light from a tungsten halogen lamp 4 as a light source is reflected to light an original 6 as a lighted body through metallic reflecting mirrors 1, 2 and 3. On the surfaces of those reflecting mirrors 1, 2 and 3, thin dielectric films 10a and 10b are formed which when the light from the lamp is reflected, reduces the reflection of light in the near infrared wavelength range.
