Product Description

Product Description

The Kerns Technology 300mW 1064-2050nm Polarization Maintaining Faraday Mirror (PMFM) is a high-reliability optical component designed to reflect and rotate light polarization via the Faraday effect. Operating across a broad 1064-2050nm wavelength range (with band-specific bandwidths: ±5nm for 1064nm, ±15nm for 1550/2050nm bands), it delivers a precise 45° polarization rotation (±3° tolerance) for reflected light, ensuring polarization stability in fiber-optic systems.

Built with PM Panda Fiber and a compact φ5.5×35mm package, this mirror supports up to 300mW continuous-wave power and features low insertion loss (as low as 0.6dB for 1550nm band) and 20dB minimum extinction ratio. Its dual-axis alignment design and rugged construction enable reliable performance across -5~+70°C operating temperatures, making it ideal for suppressing back-reflections, stabilizing laser cavities, and enhancing signal integrity in precision optical setups.

Product Features

1. Broad Wavelength Compatibility

Covers 1064-2050nm (with band-specific bandwidths: ±5nm for 1064nm, ±15nm for 1550/2050nm), eliminating the need for multiple single-wavelength components.

2. Precise Polarization Rotation

Delivers 45° polarization rotation (±3° tolerance) for reflected light, maintaining polarization integrity in PM fiber systems.

3. Low Insertion Loss

Typical insertion loss as low as 0.6dB (1550nm band), minimizing signal attenuation in high-gain optical systems (e.g., fiber amplifiers).

4. High Polarization Stability

20dB minimum extinction ratio and 0.05ps maximum polarization mode dispersion reduce polarization drift caused by environmental disturbances.

5. Compact & Rugged Design

φ5.5×35mm package with 5N tensile load resistance, suitable for space-constrained industrial and laboratory environments.

6. Flexible Customization

Supports tailored options for fiber type (PM1550/PM1310/PM980), pigtail length (0.8m/1m), and connectors (FC/UPC, FC/APC, SC/UPC, etc.).

FAQs

Q1: What power level can this mirror handle?

A1: It supports up to 300mW continuous-wave power. Note that with connectors, insertion loss increases by 0.3dB, and other parameters (return loss, extinction ratio) have slight adjustments.

Q2: Can the fiber type and connector be customized?

A2: Yes. We offer fiber type options (PM1550, PM1310, PM980, etc.) and connectors (FC/UPC, FC/APC, SC/UPC, etc.), as well as pigtail type and length customization.

Q3: What is the operating temperature range?

A3: It operates reliably between -5°C and +70°C, with a storage temperature range of -40°C to +85°C, suitable for harsh industrial and laboratory environments.

Q4: How does this mirror suppress back-reflections?

A4: Its 45° polarization rotation for reflected light creates a "non-reciprocal" optical path, blocking reverse-propagating light and protecting sensitive laser sources.
