product description
The GKER Photonics Multimode Fiber Collimator (GK-MMC Series) is a high-performance optical component designed to collimate light exiting from a multimode fiber into a parallel beam. This collimator is an essential element for in-line fiber optic components, such as isolators and wavelength division multiplexers (WDMs), making it a crucial part of advanced optical systems. It is engineered with precision to deliver low insertion loss and high return loss, ensuring minimal signal degradation and maximum efficiency.
The collimator’s design incorporates a high-quality anti-reflection (AR) coating, which enhances its ability to handle high optical power levels. This feature makes it suitable for demanding applications where power handling is critical. The collimator is available with various customization options, including different lens diameters, working distances, and fiber types, to meet the specific requirements of your optical systems.
With its robust construction and reliable performance across a wide temperature range, the GK-MMC Series Multimode Fiber Collimator is ideal for both standard and specialized optical applications.
