Abstract
An optronic device fitted with a focusing mirror for projection on a visor. A plane mirror is placed between the last active component of the optronic device and the visor. The mirror is attached to a reinforcement of the device by an elastomeric seal that presses the mirror against screws screwed into the reinforcement. The ends of each pair of screws form axes about which it is possible to pivot the mirror. An identical action on each of the screws makes it possible to move the mirror in translation. Adjusting the mirror makes it possible to alter the position of the visor seen by an optical module of the optronic device, and therefore to focus the image on the visor so that it is as sharp as possible. This corrects placement errors of the visor and its curvature defects.
