Microscopic Raman device

A microscopic Raman device comprising:

• 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, wherein
• 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, and
• the second Raman scattered light is sequentially reflected by the third optical element and the fourth optical element and passes through the second optical element to enter the spectrometer.
