PROBLEM TO BE SOLVED: To provide thermal lens analytical equipment capable of stably analyzing a thermal lens. SOLUTION: The thermal lens analytical equipment 1 is provided with a rod lens 10, which irradiates a sample solution with an exciting light and a detection light; a PD 11 which detects the signal intensities of detected light, before and after forming the thermal lens 12 in the sample solution; and a computer which computes TLM outputs from the signal intensities detected by the PD 11. In the analysis, the thermal lens 12, having a distribution for the refraction index according to a propagation intensity I(r, z) of an exciting beam is approximated by an SNS laminated optical system 3 having a difference of refraction index dn as a variable, and the detection light having a chromatic aberration df as a variable is irradiated to the thermal lens 12, and then the light is received by the PD 11 with a normalized PD distance Lo as a variable, in order to obtain the TLM outputs.
