Free space optical isolators are essential components in high-speed optical transmitters and pump laser systems, providing critical isolation of backward light reflections. These isolators deliver exceptional performance with high isolation levels and minimal insertion loss.

Available in single-stage or semi-double-stage configurations centered at wavelengths including 1310nm, 1490nm, and 1550nm. Standard clear aperture diameters range from 0.40mm to 1.5mm, with packaging options including square, round, or U-shaped housings.

• Superior performance and reliability
• Customizable sizes and wavelengths
• High isolation with low insertion loss
• Low, medium, and high power options
• High power models with exit ports for return signal monitoring or beam injection

• Maintain light's linear polarization
• Reduce Nd and Yb oscillations from ASE created by amplifiers
• Prevent deleterious effects of back reflections in laser diodes
• Eliminate instability in amplified laser systems caused by ASE
