WAVELENGTH (nm)
Parallel light : Parallel Light: from a 40 mm diameter parallel light source insuring uniform
intensity over the entire active area of the photomultiplier tube.
Diffused light: Diffused light: from a 40 mm diameter parallel light source and a diffuser placed
10cm from the detector. The entire active area of the PMT is exposed.
