collimators are designed to connect onto the end of an FC/PC or SMA905
connector and contain an AR-coated aspheric lens. The distance between
the aspheric lens and the tip of the FC-terminated fiber can be adjusted
to compensate for focal length changes or to recollimate the beam at the
wavelength and distance of interest.
Fixed FC or SMA Fiber Collimators
Adjustable Fiber Collimators
