Abstract
An optical device includes a lens mirror array, in which transparent optical elements are connected to each other along a first direction, and a case, in which the lens mirror array is contained and fixed. The case includes at least three holes through which a manufacturing jig can pass. The jig can be used to press the lens mirror array in a direction intersecting the first direction at three or more positions on the lens mirror array to deform the lens mirror array to correct for possible distortions in the optical device prior to the fixing of the lens mirror array to the case.
