  2. Red dot sight - Wikipedia

    en.wikipedia.org/wiki/Red_dot_sight

    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 ...

  3. Laser sight - Wikipedia

    Singaporean soldier aiming a SAR 21 with laser sight. A laser sight is a device attached or integral to a firearm to aid target acquisition. Unlike optical and iron sights where the user looks through the device to aim at the target, laser sights project a beam onto the target, providing a visual reference point.

  4. Reflector sight - Wikipedia

    en.wikipedia.org/wiki/Reflector_sight

    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 ...

  5. Sight (device) - Wikipedia

    en.wikipedia.org/wiki/Sight_(device)

    There are also sights that actively project an illuminated point of aim (a.k.a. "hot spot") onto the target itself so it can be observed by anyone with a direct view, such as laser sights and infrared illuminators on some night vision devices, [citation needed] as well as augmented or even virtual reality-enabled digital cameras ("smart scopes ...

  6. Holographic weapon sight - Wikipedia

    en.wikipedia.org/wiki/Holographic_weapon_sight

    Holographic sights have shorter battery life when compared to reflex sights that use LEDs, such as red dot sights. The laser diode in a holographic sight uses more power and has more complex driving electronics than a standard LED of an equivalent brightness, reducing the amount of time a holographic sight can run on a single set of batteries ...

  7. Telescopic sight - Wikipedia

    en.wikipedia.org/wiki/Telescopic_sight

    The German Army G36 assault rifles have a more or less built in dual combat sighting system consisting of a ZF 3×4° telescopic sight combined with an unmagnified electronic red dot sight. The dual combat sighting system weighs 30 g (1.1 oz) due to a housing made out of glass fiber reinforced polyamide.

  8. List of laser applications - Wikipedia

    Others use an infrared diode to produce a dot invisible to the naked human eye but detectable with night vision devices. The firearms adaptive target acquisition module LLM01 laser light module combines visible and infrared laser diodes. In the late 1990s, green diode pumped solid state laser (DPSS) laser sights (532 nm) became available.

    A telescope in the Very Large Telescope system producing four orange laser guide stars. A laser is a device that emits light through a process of optical amplification based on the stimulated emission of electromagnetic radiation.
