Product Description
The Kerns Technology Low Power 300mW 1064-2050nm Polarization Maintaining Faraday Rotator is a precision optical component designed to control light polarization via the non-reciprocal Faraday effect—critical for shielding sensitive laser sources and stabilizing optical systems. Operating across an ultra-broad 1064-2050nm range (covering key wavelengths including 1064nm, 1310nm, 1550nm, and 2050nm), it delivers a 45° single-pass polarization rotation (±2° tolerance at 23°C) while maintaining strict polarization alignment in PM fiber setups.
Built with high-quality PM Panda Fiber and a compact φ5.5×35mm package, this rotator supports 300mW continuous-wave power and features industry-leading performance metrics: maximum insertion loss as low as 0.6dB (1550nm band), minimum extinction ratio of 20dB, and polarization mode dispersion limited to 0.05ps. Its dual-axis alignment design ensures consistent performance across a -5~+70°C operating temperature range, making it an ideal choice for low-power fiber amplifiers, optical sensors, and laboratory R&D setups where polarization stability and signal integrity are non-negotiable
