<p>PURPOSE:To eliminate the incident light from the side end faces of interference filters by providing light absorptive members to the side end faces thereof. CONSTITUTION:A color sensor is arrayed and loaded with the red interference filter 40, the green interference filter 41 and the blue interference filter 42 from the bottom of a package 30. The light absorptive films 43, 44 are respectively applied on the two side end faces in the longitudinal direction of the red interference filter 40. The light absorptive film 43 prevents incidence of the light past the spacing between the red interference filter 40 and the package 30 and the light absorptive film 44 prevents the incidence of the light transmitted through the green interference filter 41. The incidence of the light from the side end faces of the interference filters is thereby prevented and color mixing, etc., are prevented.</p> |
