(a) Schematic of 2p LSFM with axicon imaging. Inset shows the extended DOF using axicon imaging. Measured PSFs (b) without and (c) with axicon imaging. (d) The corresponding intensity line profiles of measured PSF and lateral FWHM factor at different axial positions: lateral (left), axial (upper right); lateral FWHM factor (lower right). Red: with axicon imaging. Blue: without axicon imaging. HWP, half-wave plate; PBS, polarization beam splitter; L1 to L9, achromatic doublet lens; and TL, tube lens. Scale bars:
