Abstract
An optical sight for a photocamera viewfinder or for an aiming device of a firearm comprises a combination of a light emitting diode (LED) with a plurality of reticle patterns applied onto the surface of the LED and selectively illuminated by connecting various portions of the reticle patterns to the source of electric power supply. The switching from one reticle pattern to another is carried out electrically without the use of moving parts of the reticles or reticle images. This ensures high accuracy in positioning of reticle elements with regard to each other, e.g., with regard to the front sight center of the partially transparent mirror, and hence, with regard to the ballistic trajectory of the bullet.
