Fiber-Free Space Isolators
Fiber-Free space isolation devices for blocking reverse transmission beams
Fiber-Free Space Isolators can be divided into two categories according to its output mode: non-expanded-beam isolator and expanded-beam isolator.
Non-expanded-beam isolator consists of birefringent crystal, Faraday rotator, half-wave plate or polarizer and collimator.It's usually used in the fiber laser system to maintain the stability of optical system effectively.
Expanded-beam isolator consists of collimator, birefringent crystal, Faraday rotator, half wave plate or polarizer and beam expander. The output beam is characterized by good beam quality and small divergence angle.
CASTECH utilizes the high-quality crystals and optical components to fabricate Fiber-Free Space Isolators with great performance. The power ranges from 1 W to 500W. The products are featured with high isolation(33dB for single-stage series and 50dB for dual-stage series), low insertion loss, excellent environmental stability and low thermal lens effect.The beam expander helps customers adjust systems magnification quickly with high-quality beam quality output.
Applications
●Fabrication of fiber laser
●Optical fiber sensor
●Laser gauge
