Thorlabs' CFC-11X-C Adjustable Focus FC Collimator, which consists of a spring-loaded, AR-coated aspheric lens mounted inside a stainless steel cell, is designed to collimate light exiting a fiber. This adjustable collimator has an FC/PC receptable. Rotation of the outer barrel of the collimator leads to translation of the housed aspheric lens along the optical axis, making it possible to adjust the distance between the lens and the tip of the fiber; the optic, which is held in place with two setscrews, can be translated by a distance equal to the "Fiber-to-Lens Distance" listed in the list below.
