KEY ELEMENTS OF A SCOPE
There are four major elements of a scope:
1. Objective Lens: This lens has three functions. First, it permits light to pass into the scope. Second, it determines
resolution. Generally, larger lenses allow more light to enter the scope and resolve details better than smaller ones.
Finally, it forms an image for the other lenses to magnify to a usable size. The image formed by this lens is upside down.
2. Erector System: The erector system serves three functions. Its primary function is to erect the image (that is, flips the
image right-side up) and align it to the reticle. During this process, primary magnification of the image takes place.
These two functions are the result of lens action.
The third function is a mechanical one. The erector lenses are housed in a tube that is fixed at one end, while the other
end of the tube is free to move and respond to dial adjustments. By moving the erector system, the point-of-aim of the
scope is adjusted to match the point-of-impact of the bullet.
3. Reticle: In simple terms, the aiming device around which the scope is built. This element replaces the iron sight system
of non-scoped rifles.
4. Ocular or Eye Lens: This element provides the secondary and final magnification of the image.
