Random Phone pic- 685nm diffraction

I was just looking though my phone and saw this pic! So I figured I'de share.
685nm putting out about 15mW. Powered by a badass "The lighting stalker" driver.



same grating I used in my 520nm vs 532nm shot as you can tell its a lot more dim at 15mW!

Nice deep cherry red colour, that is. Reminds me of a cherry cough syrup I would always have when I was sick. Doesn't remind me of the taste, though.

Like that grating. Ugh, don't remind me of that syrup.
