Abstract
PURPOSE:To obtain a color separating filter having infrared-ray shielding characteristics by forming an infrared-ray shielding layer on a transparent backing plate then providing a color separating filter layer which is org. colored layers having plural prescribed spectral transmission characteristics thereon. CONSTITUTION:An infrared ray shielding layer 3' by an inorg. interference thin film made by vacuum-depositing low refractive index material layers of SiO2, MgF2, etc. and high refractive index material layers of CeO2, ZrO2, etc., in multiple layers is formed on a transparent backing 4 such as transparent glass plate. Thence, a color separating filter 5 consisting of stripelike or mosaiclike org. colored layers having plural prescribed spectral transmittance characteristics is formed on the layer 3', whereby a color separating filter is formed. Thereby, the infrared ray shielding filter and the color separating filter are made into piece and therefore the lens system is made simple and the cost is lowered.
