Abstract

Freeform optical designs are being widely adopted in the optics industry. Applications include automotive heads-up display [1], AR/VR and short-throw projectors [2]. These applications require freeform surfaces with noncircular apertures and opto-mechanical features. Also, the optics must have high form accuracy and surface finish for acceptable performance. Consequently, successful fabrication of freeform optics is a key technology for wide adoption of these systems. See Figure 1 for a typical freeform lens.
