Infrared raman device

An infrared Raman device capable of switching and performing Raman measurement and first infrared measurement on a sample, the infrared Raman device comprising:

• an objective lens for Raman measurement;
• a first observation lens for infrared measurement;
• a laser light source that generates laser light;
• a first infrared light source that generates first infrared light;
• and
• a mirror, wherein
• the mirror is disposed at time of the Raman measurement to reflect the laser light to cause the laser light to pass through the objective lens for Raman measurement and reflect Raman light generated from the sample by the laser light that passes through the objective lens for Raman measurement and radiated to the sample, the Raman light passing back through the objective lens for Raman measurement,
• the objective lens for Raman measurement is switched to the first observation Jens for infrared measurement at time of the first infrared measurement to cause an optical axis of the first observation lens for infrared measurement to coincide with an optical axis of the objective lens for Raman measurement at the time of the Raman measurement and the first observation lens for infrared measurement is used, and
• the mirror is disposed at the time of the first infrared measurement to partially reflect the first infrared light to cause the first infrared light to pass through the first observation lens for infrared measurement and transmit the first infrared light that is reflected by the sample after passing through the first observation lens for infrared measurement and passes through the first observation lens for infrared measurement again.
