万万没想到（德国oke公司）OKE公司在哪里，

时间：2022-11-26

带你了解荷兰OKO公司

荷兰OKO公司（全名：Flexible Optical B.V.）成立于1997年，是世界上最早进行自适应光学产品研发和销售的公司之一。该公司的创始人正是微机械薄膜变形镜（MMDM）的发明人Gleb Vdovin博士。

OKO公司的主营产品是MMDM变形镜、PDM变形镜、Shack-Hartmann波前传感器等自适应光学器件。因为变形镜优良的光学性能、低廉的价格，一经推出就受到了全世界范围内自适应光学研究人员和用户的青睐。尤其是15 mm口径、37通道的MMDM最受欢迎，被称为”OKO Mirror”。
