英国Knight Optical 1020DIB25,Knight Optical带通滤波片,滤波器

Knight Optical干涉带通滤波器用于分离和传输指定的窄波长,并反射所有其他入射波长。 Knight Optical的高质量标准带宽可见类型干涉滤波器的库存范围从330NM-2000NM在不同的带宽,以满足大多数要求,如成像和仪器。这个可见范围有一个标准的45-50%的传输,但是一些普通的波长储存有一个高70%的传输(见FYJ型滤波器)。单独的滤波器是数控限制和密封形成堆栈在他们的环,确保最大的长期稳定性。虽然我们的标准库存范围是安装的,但未安装的类型与航空航天漆黑色边缘可应要求提供。英国Knight Optical所有的干涉带通滤波器都有一个传输曲线.
