Optical luminescence Yield is collected  by a quartz fiber placed in front of sample confocal with  light  spot (default BEAR,  BACH light spot can be considered) with a wide choice of incidence and collection geometries.

Acquisition modes include:

• Total  Optical Luminescence Yield (TOLY) vs energy collecting the total signal   transmitted by the optical fiber by a suitable optical detector  (default  Photon-   electron Multiplier Tube /PMT  or photo-diode). Scanning in energy beamline   monochromator excitation curves can be obtained
• Energy/Lambda  Resolved Optical Luminescence analyzing in photon energy at fixed   synchrotron excitation energy the emission spectrum by visible-near UV   monochromator in the transmission band of quartz fiber (default detection include   PMT and diode)

Fluorescence Yield can be acquired through two acquisition setups:

• Total Fluorescence Yield (TFY) acquiring by a detector (electron multipliers or   photodiode) placed in front of sample illuminated by the synchrotron beam with a   wide choice of incidence and collection  geometries
• Energy Resolved Fluorescence Yield (ERFY) acquiring by a Silicon Drift Detector   (SDD)   placed in front of sample illuminated by the synchrotron beam with a wide   choice of incidence and collection  geometries
