| 摘 要： | 主动抛光盘技术特别适用于磨制焦比大的深度非球面,能够根据需要对抛光盘面实时地主动变形成偏轴非球面来磨制非球面镜面。它具有较高的磨削速率和较大范围内的自然平滑(无切带)。用计算机控制磨制,可以像加工球面一样来加工一个深度的非球面。介绍了用国内首次研制成功的主动抛光盘对加工直径910mm、焦比F/2的抛物面镜的工艺方法的初步探讨,并给出了抛物面镜的检验方案和检测结果。

| Abstract: | Stressed lap polishing technology is applied to deep aspheric mirror. It can active deform the lap surface to become an off-axis asphere according different lap position on mirror surface and different angle of lap. Because the curvature is difference not only on different position on aspherical surface, but also on different direction, so the classical large polishing lap can't keep the lap surface as same as the aspherical mirror surface when it moves and spins on the mirror surface. Comparing with traditional polishing methods, it has high polishing speed and natural smooth. It is computer-control polishing technology, using it optician can polish a deep aspherical mirror just as to polish a spherical mirror. How to use stressed lap was introduced to polish 910mm, F/2 paraboloidal mirror and explore the optical technology on the basis of stressed lap. The testing method and testing result were given. |
