Calcite.

 

 

 

 

 

 

 

 

The peak at 1090 cm-1 is normally the highest in the spectrum but due to the sensitivity decrease of the camera at higher wavelength it is of lower intensity than the peaks at short wave numbers.

Quartz

 

 

Due to the high steepness of the Semrock edge filers, the peak at 120 cm-1 is visible.
