Suppress optical feedback

Optical isolators with a preset output polarizer for the rotator glass. In the A configurations, the “input end” is the end with the setting ring. In the B configurations, the input polarizer is aligned for vertical input polarization and the output polarizer is at 45 degrees to the input.

Polarization-Independent Optical Isolator

Optical isolator with a preset output polarizer for the rotator glass.  

A configuration: The “input end” is the end with the setting ring.  

B configuration: The input polarizer is aligned for vertical input polarization and the output polarizer is at 45 degrees to the input.

C configuration: If the source is polarized horizontally, you can easily remove both the setting screws at the base and turn the isolator by 90 degrees so that the two threaded holes on the cylinder are aligned with the fastening screws on the base.
