Aspherical Lens |

 |
For the special camera lens, only use spherical lens with
constant curvature cannot make the aberration
correction to the degree of customer
satisfaction. However, aspherical lens has
better curvature radius and the curvature radius
changes with central axis, which can maintain
good aberration correction, improve the optical
quality and reduce the optical element, so as to
reduce the design cost. Aspheric lens has unique
advantages compared with spherical lens, so it
has been widely used in optical instruments,
image, photoelectron industry. CNI use high
precision milling and polishing equipment to
ensure better surface profile, and provide Zygo
interferometer and Taylor-hobson contourgraph
test report. |
