发帖数: 34 | 1 We have a system for bulk fluoresce and Raman. Is it possible to
make it do thin film Raman? What kind of adjustment we have to
make? We have tried for some time, no luck so far.
The main prolems is that we cannot get sufficient signal from the
film. We are getting all signal from the substrate.

发帖数: 10 | 2 As far as I know, it is ipossible for you to measure the Raman signal
by using your system. Your system does not have such function for thin film.
The signal from the thin film is very weak. you can get the signal of the
substrate, however, the signal is not enough for detecting in such system.

Lots of things have to be taken care of for thin film scattering.
Reconfiguring the system is almost like making a new one.
