A view through a Tasco ProPoint red dot sight. The mid- to late 1970s saw the introduction of what are usually referred to as red dot sights, a type that gives the user a simple bright red dot as an aiming point. [27] The typical configuration for this sight is a compact curved mirror reflector design with a red light-emitting diode (LED) at ...
The Red Dot Design Award goes back to the association Haus der Industrieform e.V. (House of Industrial Form e.V.), which was founded on July 30, 1954 in Essen. [1] Starting in October 1955, Haus Industrieform began hosting a permanent exhibition at the Kleines Haus der Villa Hügel as well as hosting a design award.
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 ...
Aimpoint is a manufacturing company founded in 1974. [1] Their primary products are reflector (or reflex) sights, specifically the red dot sight sub-type. In 1975 they introduced their first product, [2] the "Aimpoint Electronic" red dot sight, based on a design by Helsingborg engineer John Arne Ingemund Ekstrand. [3]
Photons interact with an object by some combination of reflection, absorption and transmission. Some materials, such as plate glass and clean water, transmit much of the light that falls on them and reflect little of it; such materials are called optically transparent. Many liquids and aqueous solutions are highly transparent.

A see-through display or transparent display is an electronic display that allows the user to see what is shown on the screen while still being able to see through it. The main applications of this type of display are in head-up displays , augmented reality systems, digital signage, and general large-scale spatial light modulation .
The well-known Magic Eye books feature another type of autostereogram called a random-dot autostereogram (see § Random-dot, below), similar to the first example, above. In this type of autostereogram, every pixel in the image is computed from a pattern strip and a depth map. A hidden 3D scene emerges when the image is viewed with the correct ...
