The GKER Photonics Single Fiber Collimator (GK-C Series) is an advanced optical component designed to enhance the performance of fiber optics systems, including isolators and wavelength division multiplexers (WDMs). This high-precision collimator delivers exceptional optical performance with low insertion loss and high return loss, ensuring minimal signal degradation and optimal signal integrity.

Crafted with a focus on versatility, the GK-C Series accommodates a wide range of operating wavelengths—1310 nm, 1480 nm, and 1550 nm—making it suitable for various applications. It supports different working distances from 5 mm up to 500 mm, offering flexibility to meet specific system requirements. The collimator is engineered with advanced anti-reflective (AR) coating and robust construction, allowing it to handle high optical power levels up to 3W, depending on the configuration.

Key features include a typical insertion loss of 0.25 dB and a minimum return loss of 55 dB, ensuring high-quality signal transmission. The collimator's beam diameter is precisely controlled, ranging from 0.45 mm to 0.95 mm, based on the working distance. Available with either metal or glass tube holders and various lens types, it is designed to meet diverse application needs with reliability and durability.

Ideal for integration into high-performance fiber optic systems, the GK-C Series collimator is suitable for fiber optic communication networks, wavelength division multiplexing systems, optical testing and measurement, and high-power laser applications. Its combination of low loss, high return loss, and power handling capabilities makes it a valuable component for achieving superior optical performance in demanding environments.
