利用光学系统中特有的等光程面设计了一种光纤准直透镜,可以实现光纤出射光束的扩柬和准直。在分析构成原理的基础上,利用CODEV软件模拟仿真了该准直透镜,并分析了系统的像差和衍射极限。
An optical collimating lens is designed using the characteristic of the aplanatic refracting surface. It can be used to implement beam of light of fiber expandedness and collimation. On the basis of the analysis of fabricating principle, the performance of this optical collimating lens is simulated and the parameters of it are designed by the optical software, CODE V. In addition to, the diffraction limit and aberration of this collimating system are analyzed.
