With an ever increasing  collection of new, rare and interesting micro specimens we decided to invest in our own custom built  Raman 532 Spectrometer, originally  intended for our own use but we have decided that we will be offering this as a service once a commercial licence is in place for the new software that is being developed.

Watch here for future developments..
