High Performance Raman Microscope for Geology
Raman microscopy is an information rich way to characterize your samples in life sciences, geology, nanotechnology, semiconductor, forensic science and any other application where accurate chemical identification is needed.

DeltaNu is the price/performance leader in Raman microscopy.
Our ExamineR™ system comes with your choice of wavelength modules – 785nm or, coming soon, 532nm. Our patent pending design puts the Raman module on top of the microscope and changing wavelengths is as simple as switching modules – no more tedious laser, filter, grating, and fiber optics changes like other microscopes. And, with the Raman module on top, the ExamineR’s footprint is the smallest in the industry.

Hanna Basin Amber – Amber varies greatly with location and age. The Hanna Basin in south-central Wyoming contains a combined thickness of roughly 11.5 km of Upper Cretaceous and Paleocene strata. Raman spectroscopy provides a large amount of information about amber. This study shows the age dependent 1650 cm^-1 C=C feature relative to the 1450 cm^-1 C-H scissor modes. The ExamineR also clearly shows the carbonyl features due to oxidation and esterification. Modern pine resin is shown for comparison. Modern pine resin does not show oxidation products and has a relatively large intensity ratio of the 1650 cm^-1 features to the 1450 cm^-1 band.

Lichen induced changes in feldspar? – This feldspar sample was found in the Sherman granite deposits east of Laramie, WY. When examined with DeltaNu’s Raman microscope a freshly cleaved sample shows symmetric T-O stretches and O-T-O deformations indicative of a K-feldspar (Microcline). The same specimen shows peak shifts of +7 cm^-1 for the 478 cm^-1 peak and -3 cm^-1 for the 515 cm^-1 peak near lichen growths. These shifts are indicative of Ca-feldspar (Anorthite).
