Sharp 488 VS Tiffany blue

Ooohh! I have measured 30 of these new Sharp diodes for wavelength and I can tell you for certain that only a few are low enough to give you 488nm. You need a spectrometer to find them. I don't understand why this laser doesn't have an adjustable focus. These diodes are single mode and have great divergence specs if focused properly.
