Pre-aligned collimators and expanders for large optic systems   

Optical Surfaces Ltd has introduced a novel approach to large-diameter optical systems with its pre-aligned beam collimator and beam expander modules. Traditional solutions for long focal length or large-diameter optics often involve bulky, heavy, and costly reflective systems. Optical Surfaces’ modular, lightweight kits overcome these limitations while maintaining precision and stability.

The company’s pre-aligned beam collimator kits feature a new kinematic mounting system, enabling faster, more accurate, and highly reproducible assembly of large optical systems. High performance is achieved through a novel mounting technique, delivering a zero expansion parabolic mirror better than lambda /10.

Beam expanders follow a similar concept. While enclosed pre-aligned optical systems work for diameters up to 200 mm, larger systems become impractical due to size and weight. Optical Surfaces’ pre-aligned beam expander modules, suitable for optics up to 500 mm, include fully mounted primary and secondary mirrors that come pre-set and aligned. This eliminates the need for complex five-degree-of-freedom setups, reducing installation from days or weeks to just a few hours.

By combining pre-alignment with kinematic mounting, Optical Surfaces provides researchers and engineers with a practical, cost-effective solution for building large optical systems quickly without compromising precision.
