Product description

Designed for applications in fiber lasers, sensing, biomedical, military, and avionics, this couple utilizes G&H’s low-loss fused fiber technology.

No light leaves the fiber, therefore no alignment is required and there are no unwanted reflections. Furthermore, the output fiber pigtails may be directly integrated into beam delivery systems.

All variants are available on a custom basis, so please contact us to discuss your specific requirements.
