Figure Lengend Snippet: 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).

Article Snippet: Refer to depicting the essential elements of a large-angle optical raster scanning (LAORS) system, primarily comprising: a. a typical pulsed laser source with an adequate repetition rate (Fidelity 2, Coherent, USA), b. a raster scanning unit with a resonant scanner (CRS 4 kHz, driver: 311-149887) for fast X-axis and a galvanometer scanner (8320K, driver: MicroMax 671) for slow Y-axis (both from Cambridge Technology, USA), c. a general scan lens (LSM05-BB, Thorlabs, USA) with an effective focal length (EFL) of 110 mm, d. a dedicated tube lens was custom designed combining three plano-convex lenses (Edmund Optics: 86-925), each with clear aperture and EFL of 73.5 mm and 500 mm, respectively, resulting in a combined EFL of 166.7 mm, e. a high-NA and low magnification objective lens (Olympus XLUMPlanFl, 20×/0.95W) with an EFL of 9 mm.
