    Abstract: PROBLEM TO BE SOLVED: To provide a spectral module which accurately detects lights of a wide wavelength range or lights of a different wavelength range by preventing an enlargement.SOLUTION: Since a spectral part 8 and a light detecting element 9 are provided as well as a spectral part 4 and a light detecting element 5 in the spectral module 1, a detecting sensitivity is improved to the lights of the wide wavelength range or the lights of the different wavelength range. Further, between a light detecting part 5a and a light detecting part 9a, a light passing hole 5b and a light absorbing layer 12 are provided and a reflecting part 7 is provided so as to be opposed to the light absorbing layer 12 (namely, a range R), so that the enlargement can be prevented. A disturbance light Lis absorbed by the light absorbing layer 12. Even when a part of the disturbance lights Lpasses through the range R of the light absorbing layer 12, since a part of the lights is reflected to the range R side by the reflecting part 7 provided so as to be opposed to the range R, the generation of stray lights caused by an incidence of the disturbance lights Lis suppressed.

    Abstract: PROBLEM TO BE SOLVED: To provide a spectroscope manufacturing method capable of easily manufacturing highly reliable spectroscopes. SOLUTION: A box body 5 resin-molded in such a way as to have: an external shape of a rectangular parallelepiped; a pair of grooves in its bottom surface; and a hemispherical recession part 10 is prepared. A photo-curable resin agent 27 is applied to a region 12 in a bottom part of the recession part 10 of the box body 5. A light-transmitting mold 28 in which a plurality of grating grooves are arranged and formed along a prescribed direction in its bottom surface is pressed to the applied resin agent 27 to irradiate light to cure the resin agent 27 and provide the region 12 of the recession part 9 with a grating 29 in which the plurality of grating grooves are formed. A reflecting film 15 is provided by depositing Al, Au, etc. in such a way as to cover the grating 29. A photo-detection element 4 is housed in the package 2. COPYRIGHT: (C)2010,JPO&INPIT
