Know Your Scope
Riflescopes have become far more sophisticated over the years,
but the four most basic parts have remained the same.
Workings from front to back are:
1. The objective lens (or front lens) is critical to a superior
sight picture.
2. The internal erector lenses which rights 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.
HOW SCOPES WORK
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. Your
AIM scope was designed, manufactured, and tested to ensure
that, when properly mounted and sighted-in on your firearm, you
will enjoy exceptional performance. A solid mount is critical to
satisfactory performance of your scope. If you have problems
or questions, please contact AIM Product Service (see page 40,
or 43).
