Abstract:
PROBLEM TO BE SOLVED: To provide a highly reliable spectroscopic module.SOLUTION: In a spectroscopic module 1 according to the present invention, when light L1 traveling to a spectroscopic part 4 passes through a light passage hole 50, only light which has passed through a light incident side part 51 tapered toward a side of the spectroscopic part 4 and which has been incident onto a light emission side part 52 formed so as to be opposed to a bottom surface 51b of the light incident side part 51 is emitted from a light emission opening 52a. Since stray light M incident onto a side surface 51c and the bottom surface 51b of the light incident side part 51 is therefore reflected to a side opposite to the light emission side part 52, it is possible to reduce incidence of the stray light onto the light emission side part 52. It is therefore possible to improve reliability of the spectroscopic module 1.
Abstract:
PROBLEM TO BE SOLVED: To provide a spectroscopic module manufacturing method and a spectroscopic module capable of making light appropriately incident onto a main body part. SOLUTION: A photo-detection unit 10 constituted by pasting a photo-detection element 5 and a light transmission plate 56 to each other is pasted to the front surface 2a of a substrate 2 by an optical plastic agent 63 in the method for manufacturing the spectroscopic module 1. Since a light passage hole 50 of the photo-detection element 5 is covered with the light transmission plate 56 at this time, the optical plastic agent 63 is prevented from entering the light passage hole 50. Since the light passage hole 50 is formed in a semiconductor substrate 91 after the semiconductor substrate 91 provided with a photo-detection part 5a and the light transmission plate 56 are pasted to each other at the preparation of the photo-detection unit 10, it is possible to reliably prevent anything that could cause the occurrence of refraction, scattering, etc. from entering the light passage hole 50.

Abstract:
PROBLEM TO BE SOLVED: To provide a spectroscopic module which is highly reliable.SOLUTION: A spectroscopic module 1 is so configured that when light L1 traveling to a spectroscopic part 4 passes through a light passage hole 50, and only light which passes through a light incidence-side part 51 which is tapered toward the side of the spectroscopic part 4, and enters a light projection-side part 52 formed opposite to a bottom surface 51b of the light incidence-side part 51 is emitted from a light exit opening 52a. Consequently, stray light M made incident on a side face 51c and the bottom surface 51b of the light incidence-side part 51 is reflected to the opposite side from the light projection-side part 52, so the stray light is stopped from entering the light projection-side part 52. Therefore, the spectroscopic module 1 can be improved in reliability.
