What is Aspheric Technology?
All of Fujinon’s Broadcast and HDTV ENG/EFP style lenses feature Fujinon’s latest technological advancement, AT2, which combines the company’s exclusive Aspheric Technology with a new inner focusing system to increase the performance of each lens. A single aspheric element reduces distortion at wide angles, improves corner resolution, reduces glare and reflections, and allows chromatic aberration to be managed throughout the zoom range, rather than simply optimized at specific points. Aspheric elements gain their advantages from the way light passes through them. Light passing through the periphery of a spherical element falls on a different point on the focal plane than light passing through the center (spherical aberration). This requires additional elements to correct. Since light passing through aspheric elements focuses at the same point on the focal plane, additional elements are not needed. Lenses with aspheric elements eliminate the additional weight and space required by the c
