    摘要: An optical device is fitted into a casing (2) in a state in which a pair of lenses (6, 8) have the same optic axis (Ra). The casing (2) includes two identically shaped casing halves (1A, 1B), with the pair of lenses (6, 8) being embraced and held by the two casing halves in a state in which a gap (S) is left between the surfaces of the two casing halves.
