The Telrad, a reflector sight for astronomical telescopes introduced in the late 1970s. Reflector sights have been used over the years in nautical navigation devices and surveying equipment. Albada type sights were used on early large format cameras, "Point and shoot" type cameras, and on simple disposable cameras. [30]
A red dot sight is a common classification [1] for a non-magnifying reflector (or reflex) sight that provides an illuminated red dot to the user as a point of aim. A standard design uses a red light-emitting diode (LED) at the focus of collimating optics , which generates a dot-style illuminated reticle that stays in alignment with the firearm ...
Mark III free gun reflector sight mk 9 variant. Another type of optical sight is the reflector (or "reflex") sight, a generally non-magnifying optical device that allows the user to look through a glass element and see a reflection of an illuminated aiming point or some other image superimposed on the field of view. [7]
Reflector sights consisting of a 45-degree angle glass beam splitter that sat in front of the pilot and projected an illuminated image of an aiming reticle that appeared to sit out in front of the pilot's field of view at infinity and was perfectly aligned with the plane's guns ("boresighted" with the guns). The sight sat some distance away ...
In 1900, Grubb invented the reflector or "reflex" sight, [5] [6] a non-magnifying optical sight that uses a collimator to allow the viewer looking through the sight to see an illuminated image of a reticle or other pattern in front of them that stays in alignment with the device the sight is attached to (parallax free).
The Aimpoint CompM4 is a "tubed" style reflector (reflex) sight that uses a red light-emitting diode (LED) at the focus of a mirror type optical collimator to produce an aligned red aiming spot (what is commonly called a red dot sight). There are a total of 16 brightness settings for the LED, the lower 7 intended for use with night vision ...
