上述光學系統能有效的校正手持光學設備因抖動造成的光學影像模糊，所以也可以應用於望遠鏡、測距儀及瞄準器等光學設備，使得因使用者雙手抖動造成的影像模糊可有效改善。此外，測距儀原本就具有測距功能，有些望遠鏡及瞄準器也可能附帶有測距功能，在具有測距功能的光學設備其雷射發射與接收系統所發射的雷射光束，可先入射本發明之光學系統的轉像光學模組(或可以稱為正立光學模組)即稜鏡組，再入射物鏡光學模組，由物鏡光學模組射出再射向被測物，從被射物反射的雷射光束循原路徑返回，先通過物鏡光學模組再經過轉像光學模組(即稜鏡組)，最終入射光接收器，亦應屬本發明之範疇。 The above-mentioned optical system can effectively correct optical image blur caused by shaking of handheld optical equipment, so it can also be applied to optical equipment such as telescopes, rangefinders, and sights, so that image blur caused by shaking of the user's hands can be effectively improved. In addition, rangefinders originally have a distance measurement function. Some telescopes and sights may also have a distance measurement function. In optical equipment with a distance measurement function, the laser beam emitted by the laser transmitting and receiving system can be incident first. The imaging optical module (or can be called an upright optical module) of the optical system of the present invention, that is, the imaging module, is incident on the objective optical module, and then emitted from the objective optical module towards the object to be measured. The laser beam reflected by the object returns along the original path, first passes through the objective optical module, then passes through the imaging optical module (i.e., the imaging module), and finally enters the light receiver, which should also fall within the scope of the present invention.
