WLS-liquid:
LAB + 5% PMP
Illumination :
LED fiber, 2.7 Vair gap ~1mm
Possible interpretation:
Flat signal part from homogeneous light distribution in cell
Increasing signal in forward direction from direct coupling of light to wls-fibers ?

Illumination :
flash lamp 310 nm, I = 5.5air gap ~2 cm
Possible interpretation:
If flash lamp works correctly,all light comes from wave length shifting
