PROBLEM TO BE SOLVED: To provide a spectrometer capable of satisfying both of ensuring of electric connection between a photodetector and outer wiring and stabilization of a position relation between a spectroscopic part and the photodetector.SOLUTION: A spectrometer 1A comprises: a package 2 having a stem 4 and a cap 5; an optical unit 10A disposed on the stem 4; and a lead pin 3 penetrating through the stem 4. The optical unit 10A has: a spectroscopic part 21 for dispersing light incident from a light incidence part 6 of the cap 5 and reflecting it; a photodetector 30 for detecting the light dispersed and reflected by the spectroscopic part 21; a support 40 for supporting the photodetector 30 so that space is formed between the photodetector and the spectroscopic part 21; a protrusion 11 protruding from the support 40; and wiring electrically connected to the photodetector 30. The protrusion 11 is disposed in a position with which the stem 4 comes into contact. The lead pin 3 is electrically connected to a second terminal part of wiring disposed in the protrusion part 11.
Abstract:
A spectroscopic module 1 is provided with a spectroscopic unit 8 and a photodetector 9 in addition to a spectroscopic unit 7 and a photodetector 4 and thus can enhance its detection sensitivity for light in a wide wavelength range or different wavelength regions of light. A light-transmitting hole 4b is disposed between light detecting portions 4a, 9a, while a reflection unit 6 is provided so as to oppose a region R in a light-absorbing substrate 2, whereby the size can be kept from becoming larger. Ambient light La is absorbed by the region R in the substrate 2. Any part of the light La transmitted through the region R in the substrate 2 is reflected to the region R by the unit 6 formed so as to oppose the region R, whereby stray light can be inhibited from being caused by the incidence of the light La.

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.
