spektroskopy for fun and everyone!

thank you greg!

i am about to get a thermal powermeter, hopefully.
but for you silicon-users (LP1), determining the wavelength would be helpful, i bet!
with my setup (40cm long) and a proper focussing lens for a small reading-point, you should be able to read to 2nm accurate. watch your optical power, which you collimate to under one mm on printed paper then! :-)
(not to forget that you will put your eyes close to that spot to read it).
that should help for power-measure, since the wavelength changes from diode to diode slightly, changes with temperature, and changes on the advertising/sticker too!

Very nicely done and interesting post! I've always been fascinated by spectroscopy, now I think I'm gonna build me one! :) Thanks very much!
