635 nm Ultra-Long-Distance Collimator1000m

The 635 nm ultra-long-distance collimator is an optical device specially designed for long-distance laser transmission and high-precision beam collimation. It adopts a long-focal-length optical structure, which can effectively reduce laser beam divergence and improve beam directivity and long-distance transmission performance. The product operates at a wavelength of 635 nm, has an effective focal length of 309.6 mm, and a nominal beam divergence angle of 0.016 mrad, making it suitable for optical systems with high requirements for beam collimation accuracy and propagation distance. The product offers two fiber interface configurations, FC/PC and FC/APC, facilitating connection and integration with different optical devices. It can be widely used in fields such as ultra-long-distance laser collimation, spatial beam transmission, long-distance diffuse reflection testing, and p
