Abstract
A wavelength-variable light source apparatus having a wavelength measurement function for measuring the wavelength characteristic of an object to be measured. In the apparatus, a CPU outputs control signals for controlling components of a light power meter section via a bus for controlling a light detection operation. When the CPU obtains light detection level data detected by the light power meter section from light passing through an object to be measured, the CPU stores the light detection level data for each wavelength in the object to be measured in an RAM and causes a display control section to display the light detection level on a display section. Further, the CPU executes wavelength analysis processing according to a wavelength analysis program stored in an ROM, analyzes the light wavelength characteristic of the object to be measured based on the light detection level data for each wavelength stored in the RAM, and causes the display control section to display the analysis result on the display section.
