Technical Specifications

Excitation Source: 150 W xenon, continuous output, ozone-free lampOptics: All-reflective, for focusing at all wavelengths and precise imaging for microsamples.

Monochromators: Single-grating excitation and emission spectrometers (standard).
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–1.
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

Detectors:
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 2 × 106 counts s–1 , < 1000 dark counts s–1.

Sensitivity: Double-distilled, de-ionized, ICP-grade water-Raman scan 3000:1 signal-to-noise ratio at 397 nm, 5-nm bandpass, 1-s integration time, background noise first standard deviation at 450 nm. 400 000 counts s–1 using these conditions.

Sample module: The sample module also has a removable gap-bed assembly for sampling accessory
replacement.

Analysis Software: FluorEssence™ and Multigroup software for data-acquisition and manipulation through the Windows ® environment.
