Date Nov. 17, 1988.A collimating mark device is provided with an infrared collimating mark intended to be observed through a sight. The infrared collimating mark is designed such that at least two V-shaped intensity distributions are positioned in a way that their respective apexes are facing one another. Despite a relatively blurred image after conversion into a visible collimating mark, the blurred visible collimating mark can be brought in a reproducible and reliable manner into coincidence with a fixed alignment mark.</p> |
