I don’t have their grating attachment, so I just used a DVD. I was able to more or less calibrate a spectrum of a compact fluorescent bulb and take some spectra. I took a spectrum of a candle previous dipped in salt water and a spectrum of a streetlight — the emission from sodium was very obvious in both. I was able to save and export the spectra. Too bad I can’t paste images in this review.
Here’s the streetlight data (wavelength and intensity)
