Collimating Lenses

Collimating Lenses

COL-UV/VIS

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 easy coupling to optical fibre assemblies and have anodised aluminum housings. The focal point can be adjusted.

COL-UV/VIS-90

The COL-UV/VIS-90 is used to make the collimated light exit under a 90 degree angle. As an option, an FC/PC connector can be offered as well. The FCR-COL is available to mount on to a 1/4“ reflection probe to focus the measurement spot on an extended distance.
