> Fiber Optic Collimators
aFor optimal collimation these packages should be used at the alignment wavelength. For some applications they may also be used within the AR coating range. Contact your local Tech Support for custom alignment packages.
bCollimated Beam Diameter: Theoretical 1/(e2) diameter @ 1 focal length from lens; fibers: 460HP (-A), SM600 (-B), SMF-28e (-C & -1550)
cMeasured beam full angle of divergence; fibers: 460HP (-A), SM600 (-B), SMF-28e+ (-C & -1550), S405 (-405)
The DCAL220FC Series of fiber optic collimators are pre-aligned to collimate a laser beam propagating from the tip of an FC/PC (2.1 mm wide key compatible) connectorized fiber with diffraction-limited performance. The collimators have a threaded exterior, which allows for a quick connection to an optical bench or within an instrument.
The DCAL220FC Series fiber optic collimators have no movable parts and are not susceptible to misalignment. The aspheric lens are pre-aligned so that it is one focal length away from the fiber tip when inserted into the collimator. The aspheric lens used have an AR coating that minimizes surface reflections.
Each collimator is fully tested and aligned at the factory for optimum performance for your long-term application use.
PLEASE NOTE: These fiber optic collimators will only perform optimally at the design wavelength.
