复制法制造光学零件有许多优点。首先,不论何种面形精度的平面、球面和非球面光学零件,在批量生产中,复制方法是一种成本较低的生产方法。此外,复制方法可制造出重量轻惯性小,焦距重复性好的光学零件。采用复制方法可使光学零件与机械零件设计成一整体,满足各种特殊需要。可以在各种基体材料上复制出光学零件。还有许多不能用普通方法 There are many advantages to making optical parts by copying. First, the replication method is a less costly method of production in mass production, regardless of the plane, sphere, and aspheric optical parts with surface accuracy. In addition, the replication method produces optical components that are light-weight, inert and repeatable. Using a copy method allows optical parts and mechanical parts designed as a whole, to meet a variety of special needs. Optical parts can be duplicated on a variety of substrates. There are many can not use the ordinary method
