Abstract: The present invention provides a highly reliable spectral module. When light L1 proceeding to a spectroscopic unit (4) passes through a light transmitting hole (50) in the spectral module (1) in accordance with the present invention, only the light having passed through a light entrance side unit (51) formed such as to become narrower toward a substrate (2) and entered a light exit side unit (52) formed such as to oppose a bottom face (51b) of the light entrance side unit (51) is emitted from a light exit opening (52a). Therefore, stray light M incident on a side face (51c) or bottom face (51b) of the light entrance side unit (51) is reflected to the side opposite to the light exit side unit (52) and thus is inhibited from entering the light exit side unit (52). Therefore, the reliability of the spectral module (1) can be improved.

Abstract: A spectral image acquiring apparatus includes an optical filter on which light is incident; an image sensor including a two-dimensionally disposed pixel array for detecting the light via the optical filter; and a signal processing unit generating a difference-value image based on a detection signal from the image sensor. The optical filter includes a diffraction grating having a lattice pattern corresponding to one or more pixels on the image sensor. The signal processing unit calculates a difference value in an amount of received light between two adjacent pixels based on the detection signal from the image sensor, and generates the difference-value image based on the difference value. The difference value between the two adjacent pixels is varied depending on a difference in an interference point on the image sensor corresponding to a diffraction angle of the light that has passed through the diffraction grating.

Abstract: In a spectroscopy module 1, a light passing hole 50 through which a light L1 advancing to a spectroscopic portion 4 passes is formed in a light detecting element 5. Therefore, it is possible to prevent the relative positional relationship between the light passing hole 50 and a light detecting portion 5a of the light detecting element 5 from deviating. Moreover, the light detecting element 5 is bonded to a front plane 2a of a substrate 2 with an optical resin adhesive 63. Thus, it is possible to reduce a stress generated onto the light detecting element 5 due to a thermal expansion difference between the light detecting element 5 and the substrate 2. Additionally, on the light detecting element 5, a first convex portion 101 is formed so as to be located at least between the light detecting portion 5a and the light passing hole 50 when viewed from a direction substantially perpendicular to the front plane 2a. Thus, when the light detecting element 5 is attached to the substrate 2 via the optical resin adhesive 63, the optical resin adhesive 63 is dammed at the first convex portion 101. Thus, the optical resin adhesive 63 is prevented from penetrating into the light passing hole 50.
