E . g . the ge lens used in planar wide - angle altazimuth , indirect ophthalmoscopy lens in ophthalmic diagnosis , zoom lens of camera , all were minor aspheric component 例如,红外广角地平仪中的锗透镜、眼科诊断用的间接眼底镜、变焦照相机镜头、刻录机光头等都是小型的非球面元件。
In the end , the actual application method is brought forward and the experiment of polishing a glassworkpiece with aspheric surface proves that the algorithms above is efficient 最后,给出抛光算法的实现框图,并按照实现框图指导实际的玻璃非球面加工,取得满意结果,验证了算法的有效性。
Now aspheric can be fast and precision grinded and generated . however , polishing process may still most influence the efficiency and accuracy of aspheric manufacture Cnc数控技术已经能够实现光学非球面元件的精密快速铣磨成型,然而,非球面抛光仍是影响非球面加工效率和精度的主要因素。
The precision of polishing of optics depends on the precision of grind . the general procedure of processing aspheric optics is coarse grinding , fine grinding , polishing and measuring 光学元件的抛光精度取决于精磨精度,非球面光学元件的加工工序简略的可分为粗磨成形、精磨成形、抛光、检测。
The new zyoptix aspheric is a customized treatment that not only preserves the aspherical shape of the cornea , but also reduces the visual aberrations such as glare and halo at night 而最新的非球面激光矫视zyoptix aspheric技术是一种个人化疗程,可有效保存角膜的非球面形状及改善手术后眩光及光环等晚间视力问题。
