红点镜(red dot sight),也叫内红点,部分型号又名反射式瞄准镜(英语:reflector sight 或 reflex sight),是一种无放大率的光学瞄具,有光亮的瞄准点(通常为一红点)。一些望远镜及内置取景器的“傻瓜相机”亦会载有红点镜。
由于红点镜中射入眼睛的光点(光射)永远与红点镜平衡,即使眼睛不在红点镜的中轴上,也能透过红点准确瞄准,可提升高速移动或身体摇晃时的射击精确度,因此被各国大量使用于军事枪械甚至战机的抬头显示器上。另外,特殊光线除了可由发光二极管生成外,亦可由自然光或极低放射性的放射物(半永久有效)提供。
与激光束瞄准差异
[编辑]红点镜与激光瞄准器不同:激光指示器是一种能将一激光红点投射于目标上的器材,而红点镜则把特殊光线由镀膜镜片(析光镜)点状反射进射手眼睛;所以目标无法发现自己身上有光点。
