Remote to close range Raman spectroscopy extends the working distance of mobile Raman spectroscopy from centimetres to remote range- up to tens of metres.
Mobile close range micro Raman spectroscopy operates at distances of a few centimetres at laser wavelengths of 532 nm and 785 nm. Remote Raman spectroscopy extends the working distance to tens of metres and can be used to conveniently analyse any spot on a monument/object from the ground level without having to move the instrument. Given the non-invasive nature of the technique, it can also be used for mapping a small region remotely (macro-Raman mapping). It can be used with complementary techniques such as XRF in close range or VIS-NIR and SWIR reflectance spectral imaging at remote range for a more comprehensive identification of a material.

Other information
-
Input: Colour image of the object or region of interest; Information on room layout and distance to the object/structure
