1310 nm Ultra-Long-Distance Collimator1000m

The 1310 nm ultra-long-distance collimator is a high-performance fiber collimation optical device designed specifically for the 1310 nm laser band. It uses Corning SMF-28e fiber and a long-focal-length optical structure, featuring large beam spot output, low beam divergence angle, and long-distance collimation. The product has an effective focal length of 315.89 mm, a nominal beam waist spot diameter of 57.5 mm, and a beam divergence angle of 0.03 mrad, which can effectively reduce laser beam expansion during long-distance transmission and improve beam propagation stability. The product offers FC/PC and FC/APC interface options and is suitable for long-distance laser transmission, free-space optical systems, precision optical measurement, scientific research experiments, and other fields.
