More Information
Summary:In the spectroscopy module 1, a light absorbing layer 6 having a light-passing hole 6a through which light L1 advancing into a spectroscopic portion 3 passes and a light-passing hole 6b through which light L2 advancing into a light detecting portion 4a of a light detecting element 4 passes is integrally formed by patterning. Therefore, it is possible to prevent deviation of the relative positional relationship between the light-passing hole 6a and the light-passing hole 6b. Further, since the occurrence of stray light is suppressed by the light absorbing layer 6 and the stray light is absorbed, the light detecting portion 4a of the light detecting element 4 can be suppressed from being made incident. Therefore, according to the spectroscopy module 1, it is possible to improve the reliability.
