详细介绍
可调激光衰减器,可变激光衰减器由ZG领xian而专业的进口激光器件和仪器旗舰型服务商-孚光精仪进口销售!精通光学,服务科学,先后为清华大学,中科院上海光机所,安徽光机所,沈阳自动化所等单位提供可变激光衰减器,laser attenuator,
连续可调激光衰减器/光束分离器可以专用于脉宽短到350fs的激光。可变激光衰减器光束分离器由两个高质量的偏振光学元件置入精密光机之中制作而成。可调激光衰减器使用高质量的偏振立体体光束分离器,把s光90度反射头透过p偏振光。使用半波片放置到入射光束,通过旋转半波片就可以获得连续可调的p光或s光。
可调激光衰减器,laser attenuator的特点:
可调激光衰减器把激光束分成两个偏振光束而且可以手动调节二者强度比
可变激光衰减器,laser attenuator透射和反射光束成90度角,方便分离操作
可调激光衰减器大动态范围
可变激光衰减器宽透过波段
可调激光衰减器光束偏离小
可变激光衰减器低色散(适合飞秒激光)
