300W High Power Expanded Beam Isolator, HP(M)EI

The high power expanded beam isolator (HPMEI) is the best Isolator designed for high power pulse fiber lasers. Two versions of design are compatible to lasers of 200W (natural cooling) and 300W (water cooling). With multiple patented technologies, the HPEI delivers unparalleled performance of aberration-free and thermal lensing-free beam quality at any output power level. It also provides high isolation to reflection coming from all spatial angles.


Features

* High isolation and low insertion loss

* PM and Non-PM types are available

* High Beam Quality

* Fiber can be customized


Applications

* Fiber Laser

* Fiber Sensor
