本文介绍一种宽视场红外传感器.它使用一个负弯月透镜元件,视场可扩大到180°以上.在这种红外传感器中有一个平面型Pb S探测元件,而且负弯月透镜镀有S_iO抗反射薄膜.
This article describes a wide field of view infrared sensor that uses a negative meniscus lens element that extends the field of view beyond 180. In this type of infrared sensor there is a planar Pb S sensing element and a negative meniscus lens is plated S_iO anti-reflective film.
