In the previous report, we proposed a straight viewing spectroscope in which a optical prism and a transmission grating are bonded. When assembling this spectrometer for elementary school children as a teaching material, there were the following drawbacks. (1) It is difficult for children to stick the prism and the diffraction grating, (2) The effect of the diffraction grating can not be obtained if the diffraction grating surface is mistakenly attached to the prism side.Therefore, we examined a spectroscope with a configuration in which a CD-R diffraction grating and an acrylic prism with a 45 ° apex angle were separated.
