紅點鏡
紅點鏡（red dot sight），部份型號又名反射式瞄準鏡（reflex sight），亦作內紅點，是一種無放大率的光學瞄具，有光亮的瞄準點（通常為一紅點）。一些望遠鏡及內置取景器的「傻瓜相機」亦會載有紅點鏡。
A view through the Mark III Free Gun Reflector Sight, first produced in 1943, used on army guns, naval guns, and as a pilot sight and a defensive gun sight on aircraft. Reticle image in this sight is produced by an optical collimator bounced off a beam splitter. The dot remains on the target even though the viewer's head is moved side to side
Tasco PDP2紅點鏡
裝有Aimpoint Comp M2紅點鏡的M4卡賓槍。
由於紅點鏡中射入眼睛的光點（光射）永遠與紅點鏡平衡，即使眼睛不在紅點鏡的中軸上，也能透過紅點準確瞄準，可提升高速移動或身體搖晃時的射擊精確度，因此被各國大量使用於軍事槍械甚至戰機的抬頭顯示器上。另外，特殊光線除了可由發光二極管生成外，亦可由自然光或極低放射性的放射物（半永久有效）提供。
