1. An analysis device that analyzes measurement target components contained within a sample, comprising:
a cell into which the sample is introduced;
a plurality of light sources including at least a first light source, a second light source, and a third light source, wherein each of the plurality of light sources outputs light at a mutually different timing;
an optical system that guides light from the respective light sources onto the cell;
a photodetector that detects an intensity of light that is transmitted through the cell; and
a signal processor that calculates a concentration of the measurement target components on an intensity-related signal related to the intensity of light detected by the photodetector, wherein the optical system comprises:
a first light source reflection mirror that reflects the light from the first light source;
a second light source optical element that reflects the light from the first light source that has been reflected by the first light source reflection mirror and transmits the light from the second light source;
a second light source reflection mirror that reflects the light from the first light source that has been reflected by the second light source optical element and the light from the second light source that has been transmitted through the second light source optical element; and
a third light source optical element that reflects the light from the first light source and the light from the second light source that have been reflected by the second light source reflection mirror, and transmits the light from the third light source, wherein each of the second light source optical element and the third light source optical element is a wedged optical element, wherein the light from the first light source is guided onto the cell by sequential reflection without having been transmitted through the second light source optical element and the third light source optical element to prevent reduction in intensity of the light from the first light source, wherein the light from the second light source is guided onto the cell by transmission through the second light source optical element and sequential reflection without having been transmitted through the third light source optical element to prevent reduction in intensity of the light from the second light source, and wherein the light from the third light source is guided onto the cell by transmission through the third light source optical element and sequential reflection to prevent reduction in intensity of the light from the third light source.
