Aspherical Lens

 

For the special advanced 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.

  Test curve:
Grinding and polishing generally applies to produce a single chip aspheric lens. With the improvement of technology, its precision is higher and higher. Precision polishing is controlled by computer, and automatic adjustment for parameters optimization.
 


Product Application: Spaceflight, precision lens, optical instrument, optoelectronics industry
Material: K9, fused silica, N-BK7.
CNI can offer different kinds of aspherical Lens upon your requests.
