I was nervous at putting the laser together I checked lots of times that everything is all perfect before I put the batteries in and yes cameras never capture the colour as it is in real time.
That diode is the same price i paid for the nda7175 i got it cheaper than that in the pic i went with the 478nm diode because 488nm is a bit to green for me unless you get a 483nm-484nm the beam on that 2w laser would be awsome tho.
