| REFERENCE | DESCRIPTION |
| SPECTROGRAPH | |
| RPA-HE 532 | HE spectrograph, to be coupled to a fibre optic probe or microscope, optimised for a laser excitation at 532 nm, provided with:
HE 532 spectrograph: -Compact, rugged spectrograph with no internal moving part. The analyser has been designed to operate with low maintenance, minimal downtime and little operator training.
-The specially developed concave holographic grating provides unsurpassed sensitivity and total spectral coverage of 3200 cm-1 with a frequency doubled NdYag laser at 532 nm.
-Spectral resolution of 3 cm-1/pixel.
-Mounted in 19” rack, inserted in a 12U box and equipped with wheels.
-Capability to integrate the laser racks with the spectrometer inside the box.
-Optional: multiplexing capability for coupling of multiple probes (up to 4 probes) at the spectrograph entrance – see multiplexing section
Multichannel air cooled (-70ÉC) CCD detector: -1024 x 256 pixels- MPP selected chip (size 26.6 x 6.7 mm)
-Spectral range: 400 – 1050 nm
-Pixel size : 26 x 26 microns
Computer and software package for data recording and analysis: -LabSpecTM spectroscopy software for Windows XP, permitting the control of the system, data acquisition and a wide range of data treatments and storage options, both for Raman spectra and mapping data. Supplied with two dongles.
-Optional: IndSpecTM software, industrial software optimised for on line monitoring of reactions. Allows for automatic data recording, analysis, storage and transfer.
