Freeform Telescopes: Mastering the Art of Optical Tolerancing & Alignment

Freeform telescope designs have advantages – increased aperture and field of view, reduced obscuration, more flexible packaging geometries – that make them the first choice for cutting-edge imaging applications. However, there is a cost in designing a system with mirrors that lack symmetry and are tilted and decentered: greater complexity in fabrication, alignment, and testing. The tolerancing process evaluates how systems perform as-built with the goal of maximizing performance while minimizing fabrication complexity and its associated cost.

This webinar surveys the tolerance types, alignment schemes, and performance metrics that matter for freeform telescopes. Together, these topics let you master the art of optical tolerancing and alignment.
