780 nm Ultra-Long-Distance Collimator1000m

The 780 nm ultra-long-distance collimator is a high-performance optical device specially designed for long-distance laser transmission and high-precision beam collimation. It adopts a long-focal-length, large-aperture 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 780 nm, has an effective focal length of 310.6 mm, a nominal beam divergence angle of 0.018 mrad, an output spot diameter of 67.3 mm, and an optical transmittance greater than 90%, providing good beam collimation and transmission characteristics. The product is compatible with Nufern 780HP fiber and offers two interface configurations, FC/PC and FC/APC, facilitating connection and integration with different optical systems. It can be widely used in fields such as ultra-long-distance laser collimation, spatial beam transmission, long-distance diffuse reflection testing, and precision photoelectric detection.
