Manufacturing Methods Make Freeform Optics More Accessible
From applications in ophthalmology, endoscopy, and microscopy — to use in head-up displays, lidar systems, unmanned aerial vehicles, and satellites — freeform optics are enhancing the performance of existing imaging systems and are key enablers in a host of lightweight, high-performance applications. Freeform optical surfaces can be defined as surfaces with no axis of rotational invariance within or beyond the optical part. This type of surface contains three or more independent...
