off-axis aberration

Using geometrical optics theory and off-axis aberration analysis , a set of crossed double strip integrators for high power CO_2 laser beam homogenizing has been designed .

利用几何光学原理和轴外像差理论，设计一种应用于大功率CO2激光陶瓷烧结实验的反射型正交双带式积分镜均束装置。

The use of the reflection type lens makes the system have superiority of less chromatic aberration and off-axis aberration .

使用反射型透镜，具有色像差和轴外像差小的优势。
