The sscope is an indispensable device for a hunter, professional or amateur who wants to hit the target accurately with each shot. The optical sight is a set of lenses mounted in a visual metal tube. Between the lenses of the eyepiece (the element facing the eye of the observer) and the lens installed at the far end of the tube, there is a wrapping system of lenses. These lenses are necessary in order for the output to form a correct, non-reversed image. In total, the scopes use more than 10 collecting and scattering lenses, grouped in a special way. It is important that all of them have reliable fixation and withstand the impact of shooting from different types of weapons.
A significant effect on the resulting image is provided by the quality of the glass for making lenses and the presence on the optical surfaces of an antireflection coating. In the serious rifle scopes on all surfaces of lenses the multilayered covering is put, that is designated by an abbreviation FMC (Fully Multi-Coated). The coating can be multilayer, but not on all surfaces (MC - Multi Coated), or simply coated (C - Coated). The amount of light transmitted depends on the type of lightening: the FMC sights give a much lighter and contrastier image in comparison with the slightly enlightened sights.
Main Features of Rifle Scopes You Should Learn More About
If you have never had rifle scopes before, it is recommended to discover how rifle scope works. One of the most important parameters affecting the lens's luminosity is the diameter of the input lens: the larger it is, the more light the lens will collect and the lighter the image will be. This should be taken into account if it is planned to shoot at dusk or under low light: for this work, it is necessary to select a sight with a large diameter of the lens. But it should be taken into account that with the increase in the size of the lens, the overall weight of the sight will also grow.
The eyepiece projects an enlarged image of objects in the field of view onto the observer's retina. In the optical sight all eyepiece lenses can be rigidly fixed in a frame: such devices are called sights with a fixed or constant multiplicity. But some models of optical sights contain a moving lens in the eyepiece, due to which the degree of magnification can be adjusted. Such sights are called pancreatic, or sights with variable multiplicity.
The name of any model of the sight is marked with numbers, separated by the "x" sign. For example, let's take "Optical sight KonuShot 4x32" as an example.
- 4x here is a fourfold increase;
- 32 - diameter of the input (frontal) objective lens in mm.
Universal sighting is a multiple of 3x-9x or 3x-12x: they are perfect for hunting. For firing at long distances or on paper targets, it is worth paying attention to the models with an increase in 6x-24x and 8x-32x. Sights with a multiplicity of more than 40x will reveal their potential only in the hands of experienced snipers. For shooting at short distances, you can use sights without magnification (so-called collimators) or with a small magnification up to 4 times.
