| 摘 要： | 根据三级像差理论,提出了单片物镜与单片目镜的像差共轭的扩束器设计方法,设计了带有非球面的两片式扩束系统,从设计的结果看出,整个系统的像差被很好地校正.为解决1.064 μm不可见波长扩束系统发散角测试问题,提出了利用线列CCD和示波器结合检验光束发散角的方法,此检验方法简便,容易实现,检测精度高.

| Abstract: | Based on the third-order aberration theory,a design method is put forward for beam expander that the aberration of an object lens and an eyepiece are conjugated,a beam expander with aspheric is designed and made up of two lens. The result of design shows that aberration of system is well corrected. In order to test the beam divergence angle for 1.064 μm invisible wavelength,the method is put forward for testing of beam divergence angle with linear CCD and oscillograph,this testing method is handy and easy to be realized,and testing precision is high. |
