780nm Long-Distance Collimator

The 780 nm long-distance collimator is a high-performance precision optical device specially designed for long-distance free-space beam transmission. It is mainly used to convert the divergent beam output from an optical fiber into a collimated beam with a low divergence angle, enabling long-distance transmission of optical signals in free space. The product adopts a precision optical collimation design, with a test wavelength of 780 nm, a bandwidth of ±30 nm, a nominal working distance of up to 300 m, a beam waist spot size of 29.79 mm ±10%, and an optical transmittance greater than 92%. It is compatible with 780HP single-mode fiber, equipped with an FC/APC connector interface, and uses a stainless steel package. It features a small beam divergence angle, high transmission efficiency, a rugged mechanical structure, and convenient installation and integration. It is suitable for free-space optical communication, long-distance optical inspection, laser collimation, fiber sensing, precision optical experiments, and other fields.
