光学非球面透镜在一些光电仪器中的应用

Application of Optical Aspheric Lenses in Some Opto-electronic Devices

使用非球面零件能大大简化光电仪器的系统，减小仪器的尺寸和重量，因而它得到越来越广泛的应用，介绍了光学非球面透镜在光盘机等光电仪器中的应用。说明了这些仪器中使用非球面透镜的原因，对透镜像质的要求，以及制造非球面透镜的材料。

: By aspherical elements, the structure of an optoelectronic device will be simplified greatly, the size and weight of the device will be reduced. The application range of aspherical element gets wider and wider recently. The applications of aspheric lenses in some optoelectronic devices, such as CD player, fiber coupling device and barcode scanner, are related. The reason for using aspheric lenses in these devices, the quality of the lens, as well as the material of it, are given.
