The ISO-04-850-MP 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 850 nm medium 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 800 to 900 nm wavelength range. The ISO-04-850-MP uses a higher damage threshold BK-7 polarizing beamsplitter (PBS) and provides double escape ports for applications where rejected power exceeds 0.5 W.

ISO-04-850-MP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850nm介质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800到900纳米的波长范围。ISO-04-850-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。
