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 ...
The optical window in a holographic weapon sight looks like a piece of clear glass with an illuminated reticle in the middle. The aiming reticle can be an infinitely small dot whose perceived size is given by the acuity of the eye. For someone with 20/20 vision, it is about 1 minute of arc (0.3 mrad). [citation needed]
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 ...
Etched "FinnDot" reticle (a regular mil-dot reticle with the addition of 400 m – 1200 m holdover (stadiametric) rangefinding brackets for 1 meter high or 0.5 meter wide targets at 400, 600, 800, 1000 and 1200 m). Reticle illumination is provided by a tritium ampoule embedded in the elevation turret.
ACOG reticles are illuminated at night by an internal tritium phosphor. Some versions have an additional daytime reticle illumination via a passive external fiberoptic light pipe or are LED-illuminated using a dry battery. The first ACOG model, known as the TA01, was released in 1987. [2] Down-range ACOG sight picture
This type of reticles, designed to hold the aim high and away from the target, are therefore called holdover reticles. Such aiming technique can quickly correct for ballistic deviations without needing to manually readjust the sight's zero, thus enabling the shooter to place rapid, reliably calibrated follow-up shots.
The reticle features a stadiametric rangefinder, ranging out to 400 meters and a single chevron as an aiming point with vertical stadia lines for a windage hold. [ 6 ] The PSO-1M2-1 has also been made in a version for the 7.62×39mm intermediate cartridge, which has the range drum marked for up to 1,000 meters.
The reticle of the SUSAT is of unusual design. Unlike the traditional crosshair layouts commonly used, which are in essence a cross intersecting the target, the SUSAT has a single obelisk-shaped post protruding from the bottom edge of the sight. This type of reticle is sometimes referred to as the "German Post".
