The collimating lenses convert divergent beams of light into a parallel beam. The lenses are optimized for the UV/VIS/NIR range, are SMA terminated for coupling to optical fiber assemblies and have anodized aluminum housings. The focal point can be adjusted. The COL-90-UV/VIS is used to have the collimated light exit under a 90-degree angle. Optionally an FC/PC connector can be offered as well.
For collimating and focusing light over larger distances, the COL-UV/VIS-25 with larger diameter is available.
For reflection probes a special adjustable FCR-COL-UV/VIS is developed to be able to create a small reflection spot on a distance.
