4Lasers平凹透镜，尺寸，焦距-20mm~-10000mm
平凹球面透镜是最普通的聚焦镜之一，其具有一个平面和一个凹面，而它们的焦距在凹面的一侧。其可以用于发散准直光束，准直会聚光束（或对汇聚到焦点的入射光束进行准直）。为了防止球面像差，准直光束应始终入射在弯曲的透镜表面上，反之亦然。平凹球面透镜的英文翻译为Plano-concave spherical lenses。
Edmund对平凹透镜有以下的分类：平凹透镜，PCV（平凹镜片）可见光范围镀减反射膜，平凹镜片镀NIR增透膜，NIR II 平凹镜片（PCV），VIS-NIR平凹镜片（PCV）,UV级熔融石英平凹透镜，平凸镜片（PCX）和单透膜组件。
4Lasers平凹透镜的主要特点：
§材质为UV级熔融石英和BK7玻璃
§标准直径：Φ12,7mm和Φ25,4mm
§焦距范围：-20 mm至-10000 mm
§可根据要求提供抗反射镀膜，定制材料，尺寸和焦距
凹透镜的主要应用：
§准直会聚光束
§发散准直光束
§继电器成像
