Reflector sight

369: 297:: depending on design constraints their field of view is the user's naked eye field of view, and their non-focusing collimated nature means they do not have the optical telescopes constraint of eye relief. Reflector sights can be combined with telescopes, usually by placing the telescope directly behind the sight so it can view the projected reticle creating a telescopic sight, but this re-introduces the problems of narrow field of view and limited eye relief. The primary drawback of reflector sight is that they need some way to illuminate the reticle to function. Reticles illuminated by ambient light are hard to use in low light situations, and sights with electrical illumination stop functioning altogether if that system fails. 132:) will appear to be sitting in front of the viewer at infinity. Reflector sights employ some form of "reflector" to allow the viewer to see the infinity image and the field of view at the same time, either by bouncing the image created by lens off a slanted glass plate, or by using a mostly clear curved glass reflector that images the reticle while the viewer looks through the reflector. Since the reticle is at infinity, it stays in alignment with the device to which the sight is attached regardless of the viewer's eye position, removing most of the 717:(also called collimating or "occluded eye gunsight" (OEG)) are simply the optical collimator focusing a reticle without any optical window. The viewer cannot see through them and only sees an image of the reticle. They are used either with both eyes open while one looks into the sight, with one eye open and moving the head to alternately see the sight and then at the target, or using one eye to partially see the sight and target at the same time. The reticle is illuminated by an electric, radioluminescent or passive ambient light source. The 306: 196: 645:(also known as "mini reflex sights" and "mini red dots") take advantage of the fact that the reflector sight's only optical element, the optical window, does not need any housing at all. This configuration consists of a base with just the necessary reflective surface for collimating the reticle mounted on it. Due to their diminished profile, open sights do not usually accommodate filters and other accessory options typically supported by tube designs. 315: 487:(HUD). The illuminated reticle was eventually replaced by a video screen at the focus of the collimating optics that not only gave a sighting point and information from a lead-finding computer and radar, but also various aircraft indicators (such as an artificial horizon, compass, altitude and airspeed indicators), facilitating the visual tracking of targets or the transition from instrument to visual methods during landings. 356:
World War II the reflector sight was being used on many types of weapons besides aircraft, including anti-aircraft guns, naval guns, anti-tank weapons, and many other weapons where the user needed the simplicity and quick target acquisition nature of the sight. Through its development in the 1930s and into World War II the sight was also being referred to in some applications by the abbreviation "

It was noted soon after its invention that the sight could be a good alternative to iron sights and also had uses in surveying and measuring equipment. The reflector sight was first used on German fighter aircraft in 1918 and widely adopted on all kinds of fighter and bomber aircraft in the 1930s. By

The idea of attaching a reflector sight to a firearm has been around since its invention in 1900. Soon after World War II, models appeared for rifles and shotguns including the Nydar shotgun sight (1945), which used a curved semi-reflective mirror to reflect an ambient lit reticle, and the Giese
