Abstract

PURPOSE: To make color separation good without decreasing sensitivity by forming a semiconductor stripe filter making use of the basic absorption of a semiconductor on a transparent substrate, coating a light transmittable dielectric thereon, and interposing the 1st and 2nd light transmittable thin film layers of the predetermined refractive indexes by way of a semiconductor filter in-between so as to closely contact the same.
CONSTITUTION: A glass substrate 11 is provided thereon with a glass layer 12 of the same quality provided with a cyan color transmitting dichroic filter 21. The 1st and 2nd light transmittable thin film layers 31 and 32 comprising ZrO2 are provided by way of a stripe filter 22 of a yellow transmitting ZnxCd1-xS thin film in-between, and a coating thin film 13 comprising a light transmittable dielectric is provided thereon. At this time, the refractive indexes of the glass substrate 11, semiconductor filter 22, coating thin film 13, and light transmittable thin film layers 31, 32 are defined as nS, nF, nD, nT1, nT2, respectively and ZrO2 is so selected as to satisfy the relations of nS<NT1<nF, nD<nT2<nF. Thereby, the color separating filter which is free from decrease in sensitivity, is good in color separation and is easy to manufacture may be obtained.
