A spectroscope is a handheld optical device which allows you to see the light distribution coming from a light source. Should be able to pick one up for under a hundred bucks.
- itishappy 2y agoI've actually looked into this in the past (for measuring the spectra of LED bulbs), but they're significantly more expensive than I expected! Gratings are cheap, but digital models seem to run upwards of $2k. Any suggestions for midrange models would be appreciated!
