代理英国Knight Optical 450DIR12光学干涉滤光片

Knight Optical的宽带和超宽带干涉带通滤波器用于隔离和传输特定窄波长，并反射所有其他入射波长。

Knight Optical 的高质量可见光和近红外滤光片库存系列从400nm到940nm，具有各种带宽，以满足从ANPR成像到闭路电视和高端监控系统的所有需求。通常，Knight Optical 的滤光片为3-7腔，大多数情况下，从200nm到FIR（3000+nm）在OD4时的截止是金属介电材料。这个宽频范围的干涉带通滤光片的标准传输率为60-70%。

所有单独安装的干涉滤光片都通过CNC划线并密封，形成在环中的堆叠，确保了最大的长期稳定性。虽然Knight Optical 的标准库存产品是安装的，但也可以根据要求提供未安装且边缘经过航空级黑色处理的类型。
