4.25 nm mm
Single-grating excitation and emission spectrometers (stand-
ard). Monochromators are f/3.5 Czerny-Turner design with
classically-ruled gratings and all-reflective optics, using 1200-
grooves/mm gratings:
Resolution 0.3 nm
Maximum scan speed 80 nm s
Accuracy ±0.5 nm
Step Size 0.0625–100 nm
Range 0–950 nm (physical)
Gratings
Excitation 330-nm blaze (220–600 nm optical range)
Emission 500-nm blaze (290–850 nm optical range)
The sample module also has a removable gap-bed assembly for
sampling accessory replacement.
Calibrated photodiode for excitation reference correction from
200–980 nm.
Emission detector is an R928P for high sensitivity in photon-
counting mode (200–850 nm). High voltage = 950 V, linearity to
