450 nm Ultra-Long-Distance Collimator1000m

The 450 nm ultra-long-distance collimator is a fiber collimator device specially designed for blue laser long-distance transmission and high-precision optical applications.The product uses Nufern 460HP fiber and a 300 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 450 nm, the output spot size is 58.1 mm, the nominal beam divergence angle is 0.015 mrad, and the optical transmittance is greater than 90%. It offers advantages such as high-efficiency optical transmission, low divergence angle, and large-spot output. It also supports 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.
