Abstract

PURPOSE:To make an optical system into one integral body and to enhance the ability for mass production of the device by molding a black box of a spectrometer, which is used for the light communication, and a base plate of an optical element in a body. CONSTITUTION:One of the upper and lower faces of the frame 1 that forms the black box is closed with a cover, the body except the cover is molded. A reflection mirror 2 and a diffraction grating 3 are formed on the inner face of the frame, slab lens media 6, 7 are provided to the entrance and exit windows 4, 5. Light entered from the optical fiber 8 is transformed into a parallel ray by the medium 6 in the vertical direction and by the reflection mirror 2 in the horizontal direction, and is applied to the diffraction grating 3. The diffracted ray is condensed by the mirror in the horizontal, and is converged to the optical fiber 9. In this way, the device is stable and solid, no adjustment is required since the optical system is in a body.
