F-Theta 扫描镜头通常用于激光扫描系统，该系统采用两轴振镜扫描指定区域，但不能容忍像平面上的角度。通过在扫描镜头中引入特定量的桶形畸变，F-Theta 扫描镜头成为像激光扫描、打标、雕刻和切割系统等图像平面上需要平坦视场的应用的理想选择。根据应用的要求，这些衍射受限的透镜系统可以针对波长、光斑尺寸和焦距进行优化，并且在整个透镜的视场中畸变保持在 0.25% 以下。

除了这些标准设计，我们还可以为您开发完整的系统，使用从激光束整形到激光束扩展和分裂的组件。
F-theta 镜头可以拍摄和形成有限距离物体的图像。提供全玻璃高性能镜头，不同镜头满足A3、A4、条码扫描功能。应用于平板扫描仪和高射仪器设备。该镜头接近衍射极限，畸变小，满足使用要求。
通过移动扫描仪来改变光束的方向。通过对焦镜头的对焦，使运动成为焦平面上的焦点之一。激光扫描可分为物镜前扫描和物镜后扫描。通常要求高的扫描设备是前物镜扫描。
1、扫描物镜属于小孔径成像差分系统，对光学分辨率要求较高。
2.因为是光电器件，所以不仅要调整白光（混合光）的像差，还要考虑R、G、B三个独立波长的像差。
3.校正畸变像差。
