The Polarization Maintaining Dual Fiber Collimator from GKER Photonics is engineered to excel in high-precision optical applications requiring stringent control over polarization and signal integrity. This advanced collimator is a fundamental component for integrating with polarization maintaining (PM) fiber optics systems, including PM isolators and PM wavelength division multiplexers (WDMs). It is meticulously designed to provide high performance with exceptional optical characteristics, including a high extinction ratio and low insertion loss.

The collimator features a unique AR coating and advanced processing techniques that enable it to handle high optical power levels with minimal performance degradation. The high extinction ratio, typically 20 dB, ensures effective polarization control, while the low insertion loss, down to 0.25 dB, and high return loss of 55 dB guarantee excellent signal transmission and minimal signal reflection. These attributes make the collimator ideal for demanding applications where precise polarization maintenance and signal integrity are critical.

Customization options are available for lens diameter, working distance, and fiber jacket, providing flexibility to meet specific system requirements. The collimator supports both transmission and reflection types, making it versatile for various optical configurations. With its robust design, the GK-HPPMC series is capable of handling continuous wave optical power up to 3 W, making it suitable for high-power optical systems. It operates reliably within a temperature range of -5°C to +70°C and is built to withstand storage temperatures from -40°C to +85°C.

This high-performance collimator is an essential component for high-end fiber optic applications, ensuring precise alignment, optimal signal integrity, and reliable operation in demanding environments.
