PM Fiber Output Isolator

PM Fibre Output Isolator

EOT's 50-200W PM fiber in/free space Faraday isolators feature clear apertures of 4mm or 12mm and central operating wavelengths of 1065nm.

These fiber in/free space isolators enable high power performance from PM fiber lasers and minimize thermal lensing for powers up to 200W. 2 models are available with power handling of up to 200W. The circular polarisation of these isolators enhances hole drilling applications.
