Abstract

PURPOSE:To obtain an imaging device of good product yields and stable performance by arraying a multiplicity of prism lenses of which the bases of rectangular prisms are made curved faces in one row by paralleling the mutual optical axes in one row and coupling these to a reflecting device. CONSTITUTION:In a prism lens P of which the base of the rectangular prism having orthogonally intersecting two faces 12, 13 and side faces 14, 15 is formed to a curved face 11, the side faces 14, 15 are roughened and subjected to blackening treatment. A multiplicity of such prisms are arrayed in one row at equal intervals by paralleling their optical axes and bringing their curved faces on the outer side, on a mounting member 18. Two mirror reflecting surfaces 19, 20 coupled at an angle of 45 deg. to the optical axis of the prism lens array A are disposed in front of said array, whereby the erecting unmagnified real image optical system is obtained.
