description The invention provides a catadioptric optical film, an imaging optical lens, an image capturing device and an electronic device. The catadioptric optical film is arranged on a surface of a substrate and comprises a reflecting film and a matt film. The reflective film includes a reflective metal film and a reflective oxide film. The main component of the reflective metal film is aluminum. The reflective oxide film comprises a first reflective oxide film and a second reflective oxide film. The matt film comprises a dark film and a first anti-reflection film, the dark film comprises a dark metal film and a dark oxidation film, the main component of the dark metal film is chromium metal, and the main component of the dark oxidation film is chromium oxide. Therefore, the effect that the light is still kept bright, clear and low in stray light after being reflected for multiple times can be achieved. 本揭示内容提供一种折反射光学膜、成像光学镜头、取像装置及电子装置，折反射光学膜设置于一基材的一表面且包含一反射膜以及一消光膜。反射膜包含一反射金属膜及一反射氧化膜。反射金属膜的主要成分为铝。反射氧化膜包含一第一反射氧化膜与一第二反射
