Abstract: A multispectral light source device includes a substrate, a plurality of light-emitting diodes, a cover body and a light guide body. The light-emitting diodes are disposed on the substrate. A plurality of waveband lights with different wavelengths are emitted by the light-emitting diodes. The cover body is disposed on the substrate, and the light-emitting diodes are covered by the cover body. The light guide body is disposed on the substrate. The light guide body has a light guide outlet. The substrate has a first diameter, the light guide outlet has a second diameter, and the ratio of the first diameter to the second diameter is in a range between 9 to 15, so that the waveband lights are moved and converged in the light guide body and emitted through the light guide outlet. As a result, the product can be miniaturized, and the handheld detection instrument can be implemented.
