From: Optical gearbox enabled versatile multiscale high-throughput multiphoton functional imaging
a The optical design of the optical gearbox based two-photon fluorescence imaging system. AOD acousto-optic deflector; L1-11, optical lenses; λ/2, half-wave plate; MA mirror array, LA lens array, CL cylindrical lenses, M1-4 mirrors, PBS polarizing beam splitter, DM dichroic beam splitter, F fluorescence bandpass filter, PMT photomultiplier tube. b The zoomed-in view of the mirror and lens array. c The design of the dual-path configuration for the polygon scanner. d Two-photon images of 0.2 µm fluorescence beads in agar. e Cross-sectional plots of the focal profile. FWHM full width at half maximum.
