Abstract
Provided is a microscopic Raman device including: a first laser light source that generates a first laser light; a second laser light source that generates a second laser light having a wavelength different from a wavelength of the first laser light; a first optical element; a second optical element; a third optical element; a fourth optical element; and a spectrometer. When the first laser light is reflected by the first optical element and passes through the third optical element to irradiate a sample, a first Raman scattered light is generated from the sample. When the second laser light is sequentially reflected by the second optical element, the fourth optical element, and the third optical element to irradiate the sample, a second Raman scattered light is generated from the sample. The first Raman scattered light passes through the third optical element and the first optical element to enter the spectrometer.
