PURPOSE:To adjust a bore sight easily by focusing laser beam to a screen placed in a focal position with a convex lens, and making the image of its printed pattern and the reference line of the reticule of an amining optical system coincident through the convex lens. CONSTITUTION:The laser beam from a laser irradiating device 1 is focused with a convex lens 2 through an objective lens used commonly with an aiming optical system 4, whereby a small printed pattern 7 is formed on a screen 3 placed in the position of a focal length (f). The image of the pattern 7 and the reference line of the reticule 5 of the system 4 are made to coincide through the lens 2 with the system 4, whereby the bore sight is adjusted easily. |
