道威棱镜有一个非常独特的性能——如果您通过棱镜观察并绕纵轴旋转,所形成的图像旋转角度将是您旋转角度的两倍。使用带平行光的道威棱镜,即可获得最佳性能。TECHSPEC® 道威棱镜的上表面为磨砂面,而最长长度(以维度B注明)则具有未开倒角的尺寸。

TECHSPEC® 道威棱镜是不加涂层的、采用增透涂层的对角面,或是镀铝的对角面。镀铝膜版的道威棱镜,采用保护性铝膜,并在对角面上涂黑漆,非常适合用于转移反射。可U型转弯入射激光光束。

当入射光线在对角面中心时,反射转移了49mm(15mm版)或75mm(25mm版)。镀铝膜版TECHSPEC® 道威棱镜可用于成像系统(视场小于维度A/维度C),以观察相机后面的区域,或周围的视角。也可以形成双像,即使一边被偏移。
