PROBLEM TO BE SOLVED: To provide a large-bore dot sight collimation device enabled to make quick and precise collimation by making binocular vision possible and minimizing the parallax.SOLUTION: A dot sight device comprises: a lighting part for irradiating a light; a reflection part 16 for reflecting at least a portion of the light irradiated by said lighting part to form an image; and connection means formed at a portion of said dot sight device, and is mounted on and demounted from a mount by the connection means. The dot sight device is characterized in that said reflection part provides a visual field having a common area capable of being simultaneously seen by the two eyes 13 of an observer. The dot sight device is characterized in that the width of said common area is larger than the width X of said reflection part.SELECTED DRAWING: Figure 4 |
