摘要
随着激光应用技术的发展,F-θ透镜被广泛地应用于红外,激光等扫描系统中。文章基于F-θ透镜的原理和特性,根据使用要求,利用ZEMAX软件,设计一个F-θ镜头。该镜头焦距160mm,视场角40°。优化设计后,像散值在像差容限范围内,满足平场要求;F-θ镜头相对畸变小于0.005%;光能利用率好,聚焦性能接近衍射极限。该镜头结构简单,符合使用要求。
With the development of laser application technology,hereby f-lens is widely application in infrared and laser scanning system.This article,based on principle and characteristics of the f-theta lens,according to the requirements of the user,with ZEMAX software,designed a f-lens.This lens’ focal length is 160 mm,and the view angle is 40 degrees.After optimization of this design,the astigmatism values in aberration capacity within the limit,meet the flat field requirements;this flens relative distortion is less than 0.005%;has a good light energy utilization rate,the focusing performance is close to the diffraction limit. This lens has a advantages of simple structure, match the requirements.
