Hi guys, very good news on the ps3 405nm chip, I thought I would have ago at a white light mix. One of a few that I have done but never on such a cheap outlay due to the main fact that until recently blue diodes were on the pricey side, due to the fact it was a last minute thing and it was rushed together I thought that it was a success due to the speed in which it was chucked together and the total power out put which would have been a lot higher if I had the right beam combiners then end result was this,
43 mw of white light could have been as high as 65/75mw with the right optics the major part being the green because I was forcing the one cube with over 100mw of green so that the cube was forced to make a split I was getting as high as 80 percent loss of light going at the wrong direction the red was ok with only a 5 percent loss, there was blue that was being wasted and not going through the cube as well which was not very efficient, I did not notice this until I looked at the photos afterwards. There was still to much blue in the beam which is good news as that means more red and green to get a higher output white light, this is down to the fact that the blue on the ps3 is 405nm and this mean like the red at 635 it has a higher energy quanta per photon due to the shorter wave length and higher frequency a bit like the visibility thing with a 635 red and a 660 red the 635 looks much brighter at the sane power output so what this means is a 405nm ps3 running at 12 mw is equal to ( I haven’t worked out the figures properly yet)38mw 473nm which is good news more blue means more red and green.So all together I had 12mw 405nm/ 20mw of 660 nm and 11mw of 532nmThe photos I have taken have not been touched up at all ( as they were) hope this helps and inspires other to build there own cheap white light all the best Kaz ps any questions feel free to ask
whats possible 12mw 405nm equivelent to approx 38mw @473nm
with 25mw 532nm and 80mw red with the right optics you should get a 120/130mw white light, i was only limited to the green because of the setup i had to make it work.
