The Telescopic Sight Parameters



A scope also called the Telescopic Sight is what we call an optical sighting device. This concept is based on a refracting telescope. A reticle is mounted over the optical system of a graphic image pattern to provide an accurate aiming point. Any system that requires aiming and good targeting have telescopic sights on them. The most popular items include rifles and other firearms. A night scope enables decent vision and aiming when it is dark. Optoelectronics needs to be implemented to build night scope systems.

The parameters involved in designing an optical Telescopic Sight depend on the type of application the scope has. It also depends on the expert yielding the weapon containing the scope. The optical parameters in general are –
  1. The Objective Lens Diameter – In order to form an image, a fixed diameter of the objective lens is required to ensure enough light creeps in to create an image. The objective lens diameter is usually measured in millimetres.
  2. Magnification – Let the focal length of the eye piece be some value ‘x’. Let the focal length of the objective be treated as some value ‘y’. The value of x/y, or the ratio of x and y gives the magnifying power of the telescopic sight. If the value of the magnifying power is around 15, then the person using the scope will feel the object is 15 times closer to him. The application the telescopic light is designed for gives the value of the magnifying power of the scope. The more the magnification required, the greater the amount of light entered should be. Another point to be remembered is that higher the magnification, higher the susceptibility of shaking. The field of view also decreases with increase in magnification.
  3. The Field of View – Light plays a major role when it comes to the formation of the virtual image on the scope. The telescopic lens concentrates the light at the object and displays it on the scope screen. The field of view is very important when it comes to rifles like the sniper rifle. The measurement is generally done in radian or angle of how many degrees can be viewed.
  4. The Exit Pupil – The diameter of the exit pupil should be equal to the fully dilated iris of the human eye before taking the shot for maximum clarity and brightness on the scope. Brightness plays a key role when the shooter takes aim and is about to shoot at the target by looking through the scope.
In case you wish to buy one of the telescopic sights, then perhaps you could do some good research and find scopes forsale online. There are a lot of companies that sell these scopes for relatively reasonable prices.

In case you are looking for a particular scope that works with only your firearm well, then finding the best Aimpoint scopes for scale could be a tedious task. If you buy it online, it is much simpler to filter out the scopes and buy what you require. The guarantee also makes it a highly safe option to go forward with.
