Hi Guys, after finishing the endurance testing of the ps3 diode for the 405nm wavelength a week or so ago I thought I would see what sort of colures I could get from mixing a ps3 diode and one of the good Doctor’s rohm diodes,

I already had disassembled the optics out of the ps3 optics housing ( ali casting) so the rest was a easy affair. Using the large cube out of the optics train out of the ps3 aluminium casting it worked very well, the red rohm diode was already set up in one of my home made heat sink modules so I just made every thing come up to that height, using blue tac to get the height,
The 405nm diode I used was the one that got damaged during the testing it now has a max out put of 7-8 mw, compared to the other ones I have that run at a stable 12 mw after optics
With a max of 8 mw to be honest I was not expecting much of a colour change due to the lower wavelength being used ( 405nm)
Obviously the red can go much higher in power output so the first thing I did was to turn down the red to around 4 mw, having the blue at the full 7-8 mw and just adjusting the red seemed the easiest way to do it.
I was very surprised with the results and trying to capture the results digitally does not do it justice from a best as I can describe a dark mauve /violet to a bright pink depending on how much red was given the pink was the nicest colour also the brightest due to the extra red given 22 mw in total, I should have used one of the 12 mw 405nm for more of a impact as the damaged one has more light scatter, this would have given me around 35-40 red(660nm) with the 12 mw (405)nm all readings are after optics and cube none of the photos have been enhanced or re colour balanced they are just as the camera took them with a incense stick slowly burning away in the corner of my work shop, if you combined two 405nm running at 12mw after optics you would get out around 90-100 nm of the coolest looking pink colours I have seen without the expenses of a white light system with dicros , all together with die4 drivers the set up I have there cost around £60, so for my next project I am going to combine 3 ps3 diodes and 1 rohm to try and get around 140 mw of pink but that wont be for around a 2-4 weeks there’s a little thing stopping me at the moment called money,
Just a thought I wonder what would happen if I mixed in some 532 around 5-8 mw with a dicro white light maybe, stay tuned and see in a few weeks,
All the Best Kaz
