The following are the first series of spectra I took with my DIY USB Sprectroscope. First here’s the lamp I’m using as a source of light for the spectrum: Definetly not a “True Light” but not that bad 🙂 That has to be taken into account. The peak you see at 825,0 nm is nothing less than the end of the image so not related to the spectrum. I have to find a way to avoid that 🙂 I have a […]

Results are not as I wanted them to be. It seems like the […]
