Raman Spectrometer: Demonstration 3mm fibre compatible

Posted on: 29/01/2016

 
See our latest technical article describing the performance of our HES 2003 Raman spectrometer. System has demonstrated a throughput advantage of over 500 times greater than a classical dispersive system. This major breakthrough represents the worlds highest throughput Raman spectrometer. System is based on a Spatial Heterodynespectrometer and has no moving parts with a resolution of ~ 4 cm-1
Making the system ideal for transmission Raman and stand off Raman observations.

 This is the final diary entry from a series of experiment demonstrating the performance of our new 3 mm fibre compatible HES 2000 spectrometer.  The system has demonstrated a resolution of ~ 4cm-1 while coupled to a 3 mm diameter. The system has not slit and has been tested with fibres of varying diameter. Figure 1 shows the required integration to achieve a given signal level as a function of fibre area. This represents a light gathering potential 500 time greater than a...

Diary of Events Date 12/12/2015
The challenge for this week was to assemble the system specifically the spectrometer. All the parts are now the laboratory and have been confirmed to be in working order. The system will is mounted in an oversized box, so that the experiments can be performed easily.
The sequence of ideal assembly is of course well known, first the spectrometer is aligned with respect to the laser, and this is then imaged onto the detector and a spectra taken.  Finally...
