520 nm Ultra-Long-Distance Collimator1000m

The 520 nm ultra-long-distance collimator is a high-performance fiber collimator device specially designed for long-distance green laser transmission and precision optical applications. The product uses Nufern 460HP fiber and a 306.8 mm long-focal-length optical system. It can convert the divergent laser output from the fiber into a collimated beam with a large spot and low divergence angle, effectively reducing beam expansion during free-space laser propagation. The central operating wavelength is 520 nm, the nominal output spot size is 58 mm, and the beam divergence angle is 0.015 mrad. It features low divergence angle, large-spot output, and long-focal-length collimation. It also provides two fiber connector configurations, FC/APC and FC/PC, and can be widely used in ultra-long-distance laser transmission, precision optical measurement, laser beam shaping, scientific research experiments, and other fields.
