摘要

The basic design physics of a 3X riflescope is discussed. Overall, it is shown that a simple paraxial analysis provided the confidence of a practical solution. The objective and relay were designed together but separate from the eyepiece. The two systems were then put together with no further optimization. The scope was manufactured and awaits further tests for optical and overall system application performance by the user. So far, the optical performance appears to be as predicted. However, further analysis was done after manufacture which showed that a much better design could have been achieved without splitting the elements of the relay lens into an air-spaced doublet. Having a cemented doublet would have helped to achieve lesser sensitivity to manufacturing tolerances even though the nominal performance is slightly lower. This shows that a simple choice for an appropriate design constrain could result in a large impact on the overall manufacturability of an optical design.
