Litiholo Laser Wavelength: 635 nm

The Litiholo Kit is awesome for making holograms at home, but it only comes with one laser. So if you make a bunch of holograms and want to display them all of at once, you are stuck.

A fellow Crash Space member (who runs a cool electroluminescent supply site) was kind enough to run the Litiholo laser through a spectogram. Most of the power is at 637 nm and 638 nm, with some power at 636 nm and 639 nm:

It turns out this is almost exactly the same spectrum as a "5mW 635nm Red Laser Module Focusable Dot" I purchased from DinoDirect for $10!
