Zemax Simulation. a) Ray-trace simulation for design of the distal optics (L3-L6). A field-of-view (FOV) of 300 × 300 μm2 can be achieved with a lateral mechanical scan angle of ± 4.5°. b), c), d) Spot size (RMS radius) of 0.33, 1.265 and 2.168 μm can be achieved at a distance of 0, 70 and 150 μm away from the center of the FOV.
