技术领域
本发明涉及成像镜头技术领域，特别是涉及一种光学成像镜头及成像设备。

ADAS系统对所搭载的车载镜头要求极高，首先要求其通光能力强，能适应外界环境的明暗变化，同时要求镜头有较高的成像清晰度，能有效分辨道路环境的细节，同时要求镜头能够对发射或反射不同波长单色光的物体(如交通信号灯、公路标识信息等)具有良好的分辨能力，以满足智能驾驶系统的特殊要求。然而，现有市场上的大多镜头均不能很好的满足上述要求。
发明内容
为此，本发明的目的在于提供一种光学成像镜头及成像设备，具有大光圈、高解像力、热稳定好以及小口径的优点。
本发明实施例通过以下技术方案实施上述的目的。
第一方面，本发明提供了一种光学成像镜头，沿光轴从物侧到成像面依次包括：具有负光焦度的第一透镜，所述第一透镜的物侧面和像侧面均为凹面；具有正光焦度的第二透镜，所述第二透镜的物侧面为凹面，所述第二透镜的像侧面为凸面；光阑；具有正光焦度的第三透镜，所述第三透镜的物侧面和像侧面均为凸面；具有负光焦度的第四透镜，所述第四透镜的物侧面为凸面，所述第四透镜的像侧面为凹面；具有正光焦度的第五透镜，所述第五透镜的物侧面和像侧面均为凸面；具有光焦度的第六透镜，所述第六透镜的物侧面在近光轴处为凸面，所述第 六透镜的像侧面在近光轴处为凹面；其中，所述光学成像镜头包含至少一个非球面透镜和至少一个球面透镜。
第二方面，本发明提供一种成像设备，包括成像元件及第一方面提供的光学成像镜头，成像元件用于将光学成像镜头形成的光学图像转换为电信号。
相较现有技术，本发明提供的光学成像镜头及成像设备，设置在光阑前的第一透镜和第二透镜均采用玻璃非球面透镜，能够让光线更平缓进入镜头，有利于改善镜头畸变并有效减小镜头的前端口径；第六透镜采用玻璃非球面透镜，能够让光线平缓的进入成像面，有利于改善镜头的球差和像散，进而提升镜头的成像品质；第三透镜和第五透镜均为双凸透镜且均采用折射率温度系数小于零的玻璃材料，对镜头高低温的对焦位置偏移量有较好的补偿效果，同时所有透镜全部使用玻璃材质，使镜头具有良好的热稳定性，使能适用于对环境比较苛刻领域，例如无人机、安防监控、车载监控等领域的需求。
综上，本发明的光学成像镜头采用六片玻璃球面与非球面镜片设计，通过合理分配各透镜的光焦度及面型搭配，使得镜头在实现良好成像质量的同时，具有小口径、大光圈、热稳定性好的优点。
