ما هي العدسة شبه الكروية?

العدسة اللاكروية هي عدسة لا تكون جوانب سطحها عبارة عن أجزاء من كرة أو أسطوانة. في التصوير, غالبًا ما تسمى مجموعة العدسات التي تتضمن عنصرًا شبه كروي عدسة شبه كروية.
The asphere’s more complex surface profile can reduce or eliminate spherical aberration and also reduce other optical aberrations such as astigmatism, compared to a simple lens. A single aspheric lens can often replace a much more complex multi-lens system. The resulting device is smaller and lighter, and sometimes cheaper than the multi-lens design.Aspheric elements are used in the design of multi-element wide-angle and fast normal lenses to reduce aberrations.
At present, our company has mastered the technology of producing aspheric lenses and has already applied that into the production of optical lenses. إن كنت مهتما, مرحبا بكم في التحقيق!
