<p>The present invention provides a highly reliable spectral module. The spectral module (1) of the present invention comprises a substrate (2) for transmitting therethrough light incident on one surface (2a); a lens unit (3), having an entrance surface (3a) opposing the other surface (2b) of the substrate (2), for transmitting therethrough the light entering from the entrance surface (3a) after passing through the substrate (2); a spectroscopic unit (4), formed with the lens unit (3), for spectrally resolving and reflecting the light having entered the lens unit (3); a photodetector (4) for detecting the light reflected by the spectroscopic unit (4); and a support unit (8), disposed between the other surface (2b) and the entrance surface (3a), for supporting the lens unit (3) against the substrate (2). Since the support unit (8) forms a gap between the other surface (2b) and the entrance surface (3a) in the spectral module (1), the other surface (2b) and the entrance surface (3a) are prevented from coming into contact with each other and causing damages, whereby the spectral module (1) can improve its reliability.</p> |
