The collimating lenses convert divergent beams of light into a parallel beam. The lenses are optimised for the UV/VIS/NIR range, are SMA terminated for coupling to optical fibre assemblies and have anodised aluminium housings. The focal point can be adjusted. The COL-UV-90 is used to have the collimated light exit under a 90-degree angle. Optionally an FC/PC connector can be offered as well.
