815 Optical Isolator

Conoptics is pleased to announce a new large aperture free-space optical isolators designed for use with Nd:YAG lasers (1064 nm).

Optical isolators, also known as Faraday isolators, are magneto-optic devices that preferentially transmit light along a single direction, shielding upstream optics from back reflections. Back reflections can create a number of instabilities in light source.

Features

• High Power Capability
• Minimize Feedback into Optical Systems
• Free-Space Input and Output Ports
• Dual Exit Ports
• Rotatable covers to optionally block rejected beam (if desired)
• Faraday Rotator Isolator tuned to 45 degrees
• (2) Glan Polarizers
• Mounting Base

Specifications

Operating Range: 1020 – 1100nm
Aperture: 8mm
Isolation > 30dB
Transmission > 92%
Damage Threshold (LTD) – CW Laser: 500W/cm2
Pulse Laser: 150MW/cm2

Additional Information (Factory Settings)

Optical Isolator input and output polarizers are pre-aligned to the rotator glass.

Input polarizer is aligned for vertical input polarization
Note: If your source is horizontally polarized, remove the two screws on the mounting base and rotate the isolator 90 degrees, re-install screws on the mounting base.

Output polarizer is set to 45 degrees from vertical.
