最近发明了一种精密加工光学表面的新方法,比起常用的设备来看快而且省。这种新方法叫做离子束成型法,是美国科尔斯曼仪器公司研究成功的。用于光学和光电仪器的制造,光学仪器和显微镜中的非球面透镜的手工生产可以用这种方法来代替,根据科尔斯曼操作说明书的介绍,通常这种非球面类型的高精度透镜的手工生产是一种慢而费的工艺,同时,也只有极少数熟练的技工能够胜任。透镜设计者都不愿意设计非球面透镜,因为制造上很困难。离子束成型法为设计者创造了条件,同时用这种方法生产价格便宜,因为这是一种连续自动的加工过程。这种方法还能够很经济地完成下列用机械加工困难的工作;
Recently a new method of precision machining of optical surfaces was invented that is quicker and cheaper than common equipment. This new method is called ion beam forming method, the United States Koestman instrument company successful research. The manual production of optical and optoelectronic devices, optical instruments and aspheric lenses in microscopes can be replaced by this method. According to Colesman’s operating instructions, this type of aspheric high-precision lens Manual production is a slow and feeble craft, at the same time, only a handful of skilled craftsmen are competent. Lens designers are reluctant to design aspheric lenses because of the difficulty in manufacturing. The ion beam forming method creates the conditions for the designer and at the same time is cheaper to produce in this way because it is a continuous, automated process. This method is also capable of economically performing the following jobs that are difficult to machine;
