![]() ![]() ![]() ![]() Unique challenges are faced by at least four different industries: those that provide optical design software as well as the hardware systems for generating (grinding, diamond turning, etc.), polishing/finishing, and measuring optical surfaces. Although symmetry typically allows sections of spheres to be fabricated and tested more simply, the successful exploitation of non-spherical optics of growing complexity offers no end of difficulties. Aspheric and freeform optics have come to play an increasingly central role across this domain. ![]() These applications vary from commercial high-volume products such as miniature mobile phone cameras to scientific instruments such as giant monolithic or segmented telescopes and industrial tools such as ultra-high performance lithographic projection systems. Production limitations are constantly being tackled to advance the many applications of precision optics.
