Simplified schematic of the combined OCT and PARS system. Component labels are defined as follows: OCT objective lens (OL-OCT), PARS objective lens (OL-PARS), collimator (COL), dispersion compensation (DC), lens (L), beam dump (BD), variable beam expander (VBE), polarizing beam splitter (PBS), quarter wave plate (QWP), dichroic mirror (DM), long pass filter (LP), aspheric focal lens (AL), photodiode (PD), 1310 nm super-luminescent diode (1310 nm SLD), mirrors (M).
