Laser Collimating Lenses

Based on your requirements, specially-adapted objectives for the collimation of diverging laser light can be developed and constructed for the spatial filters.
We would be happy to prepare an individual quotation for you based on your own requirements. Please specify the clear diameter desired, focal length or expansion ratio, wavelengths used, and your wavefront requirements.
Focussing devices can be designed, built and supplied for all lenses.
