Schematics of (a) the optical box, highlighting the UV and Vis–NIR optical paths (blue and yellow, respectively), and (b) the optomechanical setup, in which measurements are performed. Details of the various items are as follows. (1) Incoming pulses from the (355 nm) output of the OPO. (2) Incoming pulses from the (400–2750 nm) output of the OPO. (3) Energy-attenuating wheel. (4) Collimating lens. (5) High-energy optical fibre. (6) SMA port for connecting the fibre coming from the optical box. (7) SMA port for connecting the fibre coming from the xenon flash lamp. (8) Video camera. (9) Drawers containing semi-transparent mirrors, polka-dot mirrors and neutral filters. (10) Revolver objective mount. (11) 2× and 10× microscope objectives. (12) Top 15× reflective objective. (13) Sample stage. (14) Two of the three translation-stage motors of the sample holder. (15) Bottom 15× reflective objective. (16) One of the three translation-stage motors of the bottom objective. (17) SMA port for connecting the fibre to the spectrophotometer.
