Confocal Raman

Confocal Raman Microscopy (CRM)

We have a witec confocal Raman instrument (CRM200) with Ar ion laser (514.5 nm). With this we can do micro Raman and confocal Raman measurements. We have a few objectives in the range of 10X to 100X. We have a scan stage of 100 x 100 micrometers. In addition we can do fluorescence imaging. The instrument can do transmission SNOM.
