PROBLEM TO BE SOLVED: To provide an alignment device suitable to synthesize two lamps, as for a straight optical system in which a lamp bulb is fixed in alignment. SOLUTION: A concave reflection mirror 2, a light bulb 1, 1st and 2nd lens arrays 7 and 8, a rectangular or circular aperture grille 18 which is integrally formed in accordance with each cell of the lens arrays and an spherical correction lens 5 are held on a fixing table while being axially sifted at a fixed distance so as to constitute the straight optical system. Thus, such a aligning device is provided that prevents the alignment where undesired light component is taken in and that undesired light is previously cut, as for two-lamp optical illumination for reflecting light near the 2nd focus of the elliptic type concave mirror in order to add a slit plate.
