DOE扩束器

名称: DOE扩束器

型号: DOE_Expander_x25

品牌: HOLO/OR

  • 详细信息

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,大家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。

 

一般规格

Material: BK7 or Fused Silica
Transmission: ≥ 96%
Fixed Expansion factor: x2.5, x4, x5, x7 and x9.7
Product categories to be used with the DOE expander: Beam Splitter, Homogenizer / Diffuser, Top-Hat Beam Shaper, Vortex Spiral Phase Plate, Diffractive Axicon, Multi-Circles
Suitable for: 266nm to 1550nm (exists in BK7 and also in FS)
