Abstract
A focal length-correcting lens called the F-theta lens is required to compensate for the different focus on spot size due to the deflected incident laser beam. The F-theta lens was designed by the ray tracing method and fabricated by a 3D printer with polymer-based material. The designed F-theta lens is able to compensate for the focus on spot size by an incidence angle of 0 to 2 degrees. Based on the analysis of the simulation, there was almost no aberration in the $0^{\circ}C$ incidence angle, and the maximum of $50{\mu}m$ of aberration was observed at the incidence angle of $2^{\circ}$. Diffraction-encircled energy was analyzed to characterize the designed optics, and an image simulation was performed to confirm the actual image resolution.
