Collimated pigtail is a precision component used in fiber optic systems, mainly composed of pigtail and optical lens. It can collimate the optical signal in the optical fiber into parallel light output, or efficiently couple the parallel light in free space into the optical fiber.

It has the characteristics of low insertion loss and high coupling efficiency, and provides a variety of connector types and wavelength ranges for selection, suitable for laser radar, fiber laser, optical communication and other fields.
