    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.

A light-transmitting hole 5b and a light-absorbing layer 12 are disposed between light detecting portions 5a, 9a, while a reflection unit 7 is provided so as to oppose the layer 12 (i.e., region R), whereby the size can be kept from becoming larger. Ambient light La is absorbed by the layer 12. Any part of the light La transmitted through the region R in the layer 12 is reflected to the region R by the unit 7 formed so as to oppose the region R, whereby stray light can be inhibited from being caused by the incidence of the light La.

    Abstract: PROBLEM TO BE SOLVED: To provide a high-reliability spectroscopic module. SOLUTION: In the spectroscopic module, a collar part 7 is formed in a body along the fringe 6a of a diffraction layer 6 so as to be thicker than the diffraction layer 6, and a portion in contact with the collar part 7 of a curved surface 3a of a lens part 3 is a rough surface. Hereby, the diffraction layer 6 is enclosed by the collar part 7 having heightened adhesiveness to the curved surface 3a. Consequently, even if the diffraction layer 6 is thinned, exfoliation of the diffraction layer 6 from the convex curved surface 3a of the lens part 3 can be prevented. Furthermore, in the spectral module, a rear surface 7a facing to the curved surface 3a of the lens part 3 of the collar part 7 is a flat surface. As a result, even if a light enters the collar part 7, the light reaches the rear surface 7a which is the flat surface of the collar part 7. Consequently, the light to be imaged directly on a photodetection part of a photodetection element as stray light can be reduced. COPYRIGHT: (C)2011,JPO&INPIT

    Abstract translation: 要解决的问题：提供高可靠性分光模块。 解决方案：在分光模块中，沿着衍射层6的边缘6a在主体中形成轴环部分7以比衍射层6厚，并且与凸缘部分7接触的部分 透镜部3的曲面3a是粗糙面。 因此，衍射层6被具有与弯曲表面3a的粘合性增强的凸缘部分7包围。 因此，即使衍射层6变薄，也可以防止衍射层6从透镜部3的凸曲面3a剥离。 此外，在光谱模块中，面向凸缘部7的透镜部3的曲面3a的后表面7a是平坦的表面。 结果，即使光进入凸缘部7，光到达作为凸缘部7的平面的后表面7a。因此，要成像的光直接成像在光检测元件的光检测部上，作为杂散 光可以减少。 版权所有（C）2011，JPO＆INPIT
