<p>PROBLEM TO BE SOLVED: To provide a manufacturing method for an optical device which can manufacture the optical device at low cost, the reference positioning standard, the optical device, and a projector. SOLUTION: The posture of a measuring reference surface of the reference positioning standard is adjusted by using an automatic collimator The reference positioning standard is so arranged that the adjusted measuring reference surface is at a designed position and a CCD camera detect luminous flux emitted from the measuring reference surface to set a reference position. According to average optical characteristics previously obtained by a projection lens inspecting device, a correction position for the designed position is set as initialization processing and the CCD camera is moved to the correction position. The optical device is installed and while the CCD camera detects the luminous flux emitted from a light projection end surface of across dichroic prism of the optical device, the position of a liquid crystal panel is adjusted. Lastly, the liquid crystal panel is bonded and fixed with an ultraviolet-ray setting adhesive to manufacture the high-precision optical device at a low cost.</p> |
