Know Your Scope - Leupold Hunting Equipment Owner's Handbook Manual

Riflescopes have become far more sophisticated over the years, but the four
most basic parts have remained the same. Working from front to back they are:
1. The objective lens (or front lens) is critical to a superior sight picture.
2. The internal erector lenses which right the image.
3. The reticle, often referred to as the crosshair, provides the aiming point.
4. The ocular lens (or eyepiece lens) works with the other lenses to magnify
the image, provide correct eye relief, and make diopter corrections.
As light passes through and beyond the objective lens, the resulting upside
down image is sent to the internal lenses. Known as erector lenses, these
internal lenses return the image to a right-side-up position. Finally, the ocular
lens makes a final enlargement of that image and sends it on to your eye.
