For collimated beams, LASER COMPONENTS manufactures optical fibers in which a gradient-index lens is directly connected to the optical fiber. A non-adhesive process ensures a reproducibly high-quality standard. External collimators are no longer necessary with these assemblies to produce parallel directional light.
Gradient-index (GRIN) lenses are cylindrically shaped glass bodies in which the refractive index decreases continuously from the center to the edge. As a result, the emerging light beam is collimated.
In the assemblies manufactured by LASER COMPONENTS, the numerical apertures of the collimators are 0.5 and 0.2. In the standard configuration, the lenses are mounted on an SMF-28 single-mode fiber and installed in an FC connector in such a way that the ferrule directly terminates with the fiber end. In this configuration, the manufacturer offers assemblies for telecom wavelengths of 1310 nm and 1550 nm. Other connector types and bare fiber solutions are also supplied upon customer request. The company is similarly flexible when it comes to wavelengths: for example, versions for 650 nm and 870 nm are also available.
