850 nm Ultra-Long-Distance Collimator1000m

The 850 nm ultra-long-distance fiber collimating lens is a fiber collimation product designed for long-distance laser transmission and high-precision optical applications. The product uses Nufern 780HP fiber, operates at a wavelength of 850 nm, has an effective focal length of 312.4 mm, and a nominal beam divergence angle of 0.019 mrad, enabling low-divergence collimated beam output. The product features a large beam aperture and good beam directionality, and can effectively reduce beam spot expansion during long-distance laser propagation. It supports FC/PC and FC/APC connector configurations for easy connection to different fiber systems, and is suitable for long-distance laser collimation, photoelectric detection, optical experiments, laser measurement, and other fields.
