I decided to make a graphic with the different diodes we use arranged on the visual spectrum. I've seen a few graphics like this but I thought I could make a nice looking one which could be sticky'd here on the forum as a reference. Do you guys think something like this would be useful? Suggestions/criticisms welcome.

If people want to help contribute the technical info I'll add it to the graphic.



Or like this?

This will be useful!
You could add 640nm red DPSS


Here is the luminosity of different wavelengths:

In the dark (scotopic vision):



In the light (photopic vision):



When calculating luminosity on beams, not dots, rayleigh scattering must be taken into the equation. (Blue light beams are more visible then it would appear from the dots' visibility):



EDIT: Edited the graphs for easier use

Instead of "Commonly Used Visible Spectrum Laser Diodes", I would just kick out the word "Diodes" so as not to confuse people who see those DPSS wavelengths on there. Nice looking chart! It should be added to a newbs guide to lasers!

Can add 635 nm and 641 nm, those are also red diodes. (though not sure if 641 is any other than c-mount package, but anyway...)

If you want a chart of just laser diodes, you'll need to remove 532nm and 473nm - they're DPSS.

Speaking of DPSS, add 808nm. That one's pretty common.

Why not just make a chart of all commonly available wavelengths? Diode, DPSS, gas, etc...
