Six Basic Elements Form The System Of An Illuminated Sight:
I. Objective Lens:
Lens responsible for the amount of light that gets inside the scope. In illuminated
sights, the objective lens is angled, this is not a defect. It is angled for the proper
operation of the sight.
II. Image System:
A small metal tube with a 50% to 70% transmission mirror, set in a 15 degree slanted
angle.
III. Windage and Elevation System:
The image system tube is fixed at one end and free at the other closest to the objective
lens, the windage and elevation screws serve as supports for this end while providing
movement or correction to the reticle to adjust the aiming point to the real point of
impact of the bullet.
IV. Reticle:
The reticle replaces the iron sight system that usually comes with rifles. In the case of
Illuminated Sights the reticle is a projection of light forming one or more reticles in
one or more colors, depending on the reticle design.
V. Ocular Lens
:
The ocular lens seals the end of the sight closest to the eye, responsible for the final
collimation of the image.
VI. Rheostat Switch:
Next to the on/off function, it regulates the intensity of the LED diode.
