Friday + AD beams = "personal/mental-health" day (call-in-sick) ?

Beams with diffraction gratings ;)

That is just going to separate your beam into red, green and blue. They will look to be at different intensities depending on the color you are trying to get, so white will be your best color to go for with a diffraction grating.

Great photos as usual, Tero. Your diffraction grating shots were captured out further than I can get them indoors. The maxima out on the fringes are often too dim to be seen. Nice to see you were able to capture those. I do like the lake you often take your photos at as the reflections are really cool.

Hey AD,
More GREAT pics. I like the last two the best, nice colors. One day you should try to take some shots where the camera is set up looking at the laser and diffraction gratings and you will get the more spectacular "Fan" effect where you see all of the beams, not the dots

Notice how the outer fringes can't be seen when doing it like this. They are far too dim to be seen. I was very impressed by your ability to capture the higher order maxima using the opposite bank of the lake as a beam stop. Doing it at night also helps with that.

Hey AD,
Yes like that. Really nice shot. I like to get the "Fan" as low as possible over the camera to increase the effect. Over the years I have taken a bunch of outdoor fan diffraction shots in the fog, snow, and rain. It is hard to keep the actual diffraction grating from overexposing if you want the beams to be exposed correctly.
