立陶宛4Lasers公司授权维尔克斯光电在中国销售透镜系列产品，平凹球面透镜是***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。
