Abstract:
An apparatus for generating Raman scatter of a sample and measuring said Raman scatter of sample, said apparatus comprising:an excitation means for irradiating said sample and generating Raman scatter; said excitation means comprising a diode pumped solid state (DPSS) laser which emits light at wavelengths at least greater than 900 nm; a collection means for collecting said Raman scatter; a detection means comprising a dispersive means for separating said Raman scatter by respective wavelength into a dispersed signal; said detection means comprising a diode array detector for detecting said dispersed signal; said detection means comprising an entrance for transmission of said Raman scatter into said detection means; said diode array detector comprising an array of photo sensitive elements sensitive to at least light at wavelengths greater than 1200 nm.
