DOE扩束器Holoor

DOE扩束器Holoor

HOLO/OR引入了一个新模块，用于修改衍射光学元件（DOE）的某些输出参数。

该模块以放大系数减小或扩大DOE输出的整个角度。

与标准扩束器不同，我们的模块考虑了光束整形，光束分离和光束焦点元素的特性，从而以*小的像差实现了出色的效果。

该模块在以下情况下可能是有益的/适用的：

●将该模块与DOE一起使用，以创建整体功能，而单个元素很难制造该功能

●将HOLO / OR的模块添加到具有特定全角的标准，半标准或库存DOE中，以更改DOE的全角，从而避免支付任何NRE，并缩短了交货时间

HOLO / OR也能够根据客户的系统和要求定制模块。
