空間濾波器組件

使用物鏡與精密針孔，除去激光波面的噪音及失真的光學組件。

Component for converting light with noise into light with coherent wave fronts. Collects light with an objective lens and removes noise elements with a pinhole. May be used as a beam expander in combination with the collimator lens component.

一般與空間濾波器組件組合使用，把激光光束轉化為平行光束的組件。

A component for converting a laser beam into parallel light， together with spatial filter component. Employs a spherical achromatic lens for improved wave fronts. The three-axis lens holder allows easy fine-tuning of the optical axis direction. Allows accurate collimation when combined wit
