Product Description

633nm Polarization Maintaining Beam Combiner used for Optical Fiber Current Sensor

Product Description

 

A PM Beam Splitter/Combiner is a device that can combine or split light signals based on their polarization

 

• Beam combiner

  Combines two orthogonal polarization signals into a single output fiber. The goal is to increase the output power while preserving beam quality. 

   

   
• Beam splitter

  Splits an input signal into two output fibers. The power of each output port is determined by the power of the two orthogonal polarization states. 

Features
 

• High Return Loss
• Low Insertion Loss
• High Extinction Ratio
• High stability and reliability

Applications

• Fiber Sensors
• Optical Fiber Gyroscope
• Optical Fiber Current Sensor
• Coherent telecommunication systems
