Abstract: A display instrument using optical collimation for projecting data into the line of sight of an observer, comprising an optical lens which projects images of luminous objects focused at infinity onto a transparent combining glass. The luminous objects corresponding to data be displayed are positioned in the focal zone of the lens. The images are reflected by the glass into the observer''s line of sight. A reflectively deflective prism placed in the optical path between the optical zone and the luminous objects, enables the use of an optical lens of greater diameter whereby the operational characteristics of the equipment are improved.
