DIY Spectroscope

I wanted to examine the spectrum of the "Full Spectrum" CFLs (Compact Fluorescent Lamps) that I was using to "camera scan" slides and negatives. This is the DIY spectroscope I built to display the spectrums. I sort of don't think that I will be using full spectrum CFLs for camera scanning anymore. (To be continued...)

I got the diffraction grating slide from Amazon. I mounted the diffraction grating slide in the PhotoSolve Extend-a-Slide that I normally use to mount negatives and slides.
