Selected Calcium Fluoride substrates. Working with Raman spectra it is necessary that the substrate does not interfere with the results. Crystran Raman Grade Calcium Fluoride offers many advantages.
► Wide transmission range from deep UV to mid IR
► Complete flexibility of laser between 130nm to 10µm
► One single Raman peak only at 321cm-1 specific to CaF2
► No other Raman peaks to confuse the results
► Minimal fluorescence
► Durable and insoluble
