Sample detector : Gated photomultiplier with modified S5 response for operation to about 650nm. Interchangeable red-sensitive photomultiplier available for use to 900nm.

Reference detector : As standard sample detector.

Monochromator : Monk-Gillieson type monochromator

Wavelength accuracy : ±1.0nm

Waveleagth reproducibility : ±0.5nm

Spectral bandpass : The excitation slits and the emission slits can be varied and selected in 0.1nm increments.

Phosphorescence mode : Delay and gate times can be varied to measure phosphorescence. Minimum total period 13.0ms(50Hz)
