But the domestic ultra - precision machining of aspheric surface , especially the large - scale aspheric surface , is just the same as blank , which has no systemic research 而国内非球面特别是大型非球面的超精密加工还是空白,还没有形成系统的研究。
This aspheric surface measuring instrument in miniature have been used to practical production , and have exerted good influence on production quality and cost 本轮廓仪已经应用于实际生产中,在提高产品质量,降低生产成本等方面发挥了良好的作用。
This part including : the design of typical aspheric opthalmoscopy lenses , test and making of 20d single asphere lens , and discussion to the making result 包括典型非球面眼底镜的设计, 20d非球面间接眼底镜的检验加工,并对加工结果进行了讨论和评价。
Bausch lomb zyoptix z100 uses three dimensional eye tracker and iris recognition technology to provide latest aspheric treatment 博士伦zyoptix 217z100引进了三维眼球追踪器3d eye tracker及虹膜辨识技术iris recognition ,并提供最新的非球面激光矫视。
Several test results of other , nff - axis aspheric mirrors are also given . all of the mirrors have accuracy better than 1 / 40x , and have fulfilled the demands by designer 实践证明,本文的研究适用于大口径离轴非球面反射镜的加工,有效地提高了非球面的加工效率和精度水平。
