PURPOSE:To converge light without decreasing the transmissivity of the light nor causing a temperature rise by composing the three primary colors lens array plate of a mosaic primary color interference film filter 3 consisting of an optical multi-layered film formed on a glass base plate and many convex lenses adhered corresponding to filters of the three primary colors constituting the three primary colors interference film filter. CONSTITUTION:The primary color lens array plate 1 consists of the three primary colors interference film filter 3 where respective filters 3R, 3G, and 3B of the primary colors, i.e. red R, green G, and blue B on the glass base plate 2 and the convex lenses 4 formed of resin corresponding to the filters 3R, 3G, and 3B of the primary colors. Thus, the color filter is composed of the interference film filter 3. Consequently, the light can be converged on a specific position without decreasing the transmissivity of the light nor causing the temperature rise. |
