The ISO-04-980-MP-W Faraday Optical Isolator is essentially a uni-directional light valve. It is used to protect a laser source from destabilizing feedback or actual damage from back-reflected light. This 980 nm low power free space optical isolator is packaged in a compact cylindrically shaped magneto-optic device with a base plate for ease of mounting into an optical train. It has a 4 mm clear aperture and a 900 to 1030 nm wavelength range. The ISO-04-980-MP uses a higher damage threshold BK-7 polarizing beamsplitter (PBS) and provide double escape ports for applications where rejected power exceeds 0.5 W. This -W version has an added 1/2 wave plate at the output stage, so that the direction of polarization of the output beam can be rotated to a desired direction.

iso -04-980 mp - w法拉第光隔离器本质上是一个单向光阀。它是用来保护激光源不稳定的反馈或实际的损害，从反反射光。这种980nm低功率自由空间光隔离器封装在一个紧凑的圆柱形磁光器件中，基片便于安装到光学列车上。它有4毫米的光圈和900到1030纳米的波长范围。ISO-04-980-MP使用了更高的损伤阈值BK-7极化波束分离器(PBS)，并为拒绝功率超过0.5 W的应用程序提供了双重逃逸端口。这个-W版本在输出阶段增加了1/2波板，这样输出波束的极化方向就可以旋转到期望的方向。
