PRODUCT DESCRIPTION
1. SMA Collimation/Coupling Packages
Features:
123• Fiber Collimation for Single Mode Patch Cables with SMA Connectors
123• Popular SMA Connectors
123• Each Collimation Package is Factory Aligned
123• Simplifies Free-Space Laser to Fiber Coupling
These fiber collimation packages are pre-aligned to collimate light from an SMA connectorized fiber with diffraction-limited performance. Because these fiber collimators have no movable parts, they are compact and not susceptible to misalignment. Due to chromatic aberration, the effective focal length (EFL) of the aspheric lens is wavelength-dependent. As a result these collimators will only perform optimally at the design wavelength. The aspheric lens is factory-aligned so that it is one wavelength-adjusted focal length away from the fiber tip when inserted into the collimator. In addition, the aspheric lens has an AR coating that minimizes surface reflections.
These packages can also be used to couple a free-space laser beam into an optical fiber. To obtain a high coupling efficiency, the NA of the patch cable needs to be greater than or equal to the NA of the collimator, and the diameter of the focused beam needs to be smaller than the MFD/core of the fiber. Please refer to the Specs tab for suggested mounting adapters.

2. FC/APC Collimation/Coupling Packages
Features:
123• Fiber Collimation
123• Popular FC/PC Connectors
123• Each Collimation Package is Factory Aligned
123• Simplifies Free-Space Laser to Fiber Coupling
123• Simplifies Fiber Coupled Detection Systems
The SF240APC, SF260APC, SF280APC, and SF671APC Series of fiber collimation packages are pre-aligned to collimate a laser beam propagating from the tip of an FC/APC (2.1 mm wide key compatible) connectorized fiber with diffraction-limited performance at the design wavelength. The receptacle of the housing is angled, and the beam is aligned with the mechanical axis of the package, as shown in the schematic above. Because the F200-Series fiber collimators have no movable parts, they are compact and not susceptible to misalignment. Due to chromatic aberration, the effective focal length (EFL) of the aspheric lens is wavelength-dependent. As a result, these collimators will only perform optimally at the design wavelength. Theaspheric 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 aspheric lens has an AR coating that minimizes surface reflections.
These packages can be used to couple a free-space laser beam into an optical fiber. To obtain a high coupling efficiency, the NA of the patch cable needs to be greater than or equal to the NA of the collimator, and the diameter of the focused beam needs to be smaller than the MFD of the fiber. Please refer to the Technical Specs for suggested mounting adapters.
The FC/APC conectorized collimation packages are ideal for systems that are sensitive to back reflections. APC-Style connectors utilize a ferrule that has an 8° end face, and in conjunction with an ultra PC polish, provide a return loss Greater than 60 dB.
We also offer a line of adjustable collimation packages called FiberPorts that are well suited for a wide range of wavelengths. These are ideal solutions for adjustable, compact fiber couplers. For other collimation and coupling options, please contact us.
