1. An infrared Raman microscope capable of switching to and performing infrared spectroscopic analysis or Raman spectroscopic analysis on a sample on a stage, the infrared Raman microscope comprising:
an infrared spectrum display processing unit that performs processing of displaying an infrared spectrum obtained by infrared spectroscopic analysis in a graph representing a relationship between a wave number and intensity, wherein an axis of a direction of the graph represents wave numbers which comprise the wave number, and intervals between the wave numbers are equal;
a data conversion processing unit that performs processing of converting a Raman spectrum obtained by Raman spectroscopic analysis into an equal interval Raman spectrum in which data points are plotted by wave numbers at equal intervals, wherein an axis of the direction of the Raman spectrum represents a Raman shift which is a wave number difference between an incident light and a scattered light, and intervals along the axis of the direction for the Raman spectrum are not equal intervals, and wherein wave numbers of the equal interval Raman spectrum are equal intervals so as to match the wave numbers; and
a Raman spectrum display processing unit that performs processing of displaying the equal interval Raman spectrum as a graph representing a relationship between a wave number and intensity.
