The F810FC-2000 fiber collimation package is pre-aligned to collimate a laser beam propagating from the tip of an FC/PC-connectorized fiber with diffraction-limited performance at the design wavelength of 2 µm. Since this fiber collimator does not have any movable parts, it is compact and not susceptible to misalignment. Due to chromatic aberration, the effective focal length (EFL) of the doublet lens is wavelength dependent. As a result, this collimator will only perform optimally at the design wavelength. The doublet lens is factory aligned so that it is one focal length away from the fiber tip when inserted into the collimator. This distance is equal to the focal length of the aspheric lens at the design wavelength. In addition, the doublet lens has an AR coating that minimizes surface reflections.
