吸收型中性密度滤光片

Category: Neutral Density Filter | Model: 329 | Updated: 2019-07-27

Technical Specifications

Specifications for this model are coming soon — call us for measured data.

瑞诚光电吸收型中性密度滤光片,工艺采用中性灰色玻璃经过加工抛光等精密流程,表面光洁度和平行度都达到优质等级。与反射型中性密度滤光片不同的是,吸收型中性密度滤光片采用不同参数的基片材料,通过控制厚度的方法来达到不同的光衰减指标。这类滤光片表面反射很低,在可见光范围内有平直的光谱响应,可广泛用机于器视觉系统、光谱测量、成像光学系统、以及低功率激光器的光输出衰减等应用。
