Schematics of LAORS system with Zemax ray tracing

Input beam: optical pulses from a pulsed laser source; resonant mirror: CRS 4 kHz (Cambridge Technology, USA); galvanometer mirror: 8320K (Cambridge Technology, USA); scan lens: LSM05-BB, effective focal length (EFL) of 110 mm (Thorlabs, USA); custom tube lens: a combination of 3 plano-convex lenses (Edmund Optics: 86-925, EFL of 500 mm), combined EFL of 166.7 mm; objective lens: Olympus XLUMPlanFl, 20×/0.95W. Note that multiple colors are utilized to better distinguish the rays under different scanning angles by the resonant and galvanometer scanning mirrors (see Figure 2 for more information on optical performance at different scanning angles).
