    Default 445nm diode wavelength diffs

    I don't know if anyone else has noticed this, but I recently built a dual 445nm laser head and while performing the alignment I noticed one beam had a purple tint to it while the other beam had a more cyan tint.

    The diodes were purchased at different times. I checked my other 445nm diodes and all had the purple tint to the beam except the new diodes I purchased from Modwerx. Those diodes had a cyan tint.

    Whats the deal? Are there different versions of the 1W 445nm diodes? I checked the descriptions from places I ordered from and all showed they came from a A140 projector.
