I am looking for a second spectrometry camera for Raman/AFM combine. I have iDus 420 for Raman and fluorescence measurements in range: 400 - 900 nm, and would like to install another spectrometer for 900-1700nm. An Andor iDus InGaAs 1.7 microns spectroscopy camera suits well for that, but ... it is too expensive. I need a chipper alternative, may be, with worse parameters.
