1480nm Single Mode C-Lens Fiber Collimator
The 1480nm Single Mode C-Lens Fiber Collimator is a compact optical device designed to transform divergent light from a single mode fiber into a parallel collimated beam with high precision. Utilizing advanced C-lens technology, it provides low insertion loss, high return loss, and stable beam output for reliable optical performance.
Optimized for the 1480nm wavelength range, this collimator supports multiple working distances (5 mm, 50 mm, 100 mm), making it suitable for various free-space optical applications. Built with SMF-28e fiber, it offers excellent compatibility with standard single mode systems while maintaining low polarization dependent loss and consistent optical alignment.
