Optics and Sights
A crossbow or rifle optics works similarly to a telescope: It consists of a metal tube with glass lenses inside where light passes through to focus on a target point. The image point is inverted and transmitted to the erector lens, which then sends it to the magnifying lens to magnify the target image. There are two categories of optics: telescopic sights and reflector (reflex) sights. Telescopic sights, commonly known as “scopes,” are sights that use magnification to make targets appear closer to the shooter, thereby making it easier for the shooter to make a precision shot.
