Features Fiber Collimation Popular SMA Connectors Factory Aligned Multi-Element Lens Design for Diffraction-Limited Performance Simplifies Free-Space Laser to Fiber Coupling Lens Substrate: SFL6 Non-Magnetic Stainless Steel Housing The F810SMA-1550 fiber collimation package is pre-aligned to collimate a laser beam propagating from the tip of an SMA-connectorized fiber with diffraction-limited performance at the design wavelength of 1550 nm. 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.
