Mitsubishi ML520G71...Red Holy Grail or Flashlight Fail ??

[kiyoukan]

thats a bit far but for what you get its worth every cent. actually after seeing this im going to layout my setup with lots of more room for the reds in case i want to combine 2 reds with correction optics. with that long of a FL could you only need one set of dr.lava lenses? just send them threw the pbs then into them? as long as you use a wave plate right? to keep the beam pattern the same? that could lower the cost a good amount.

I'm imagining some people are saying to themselves 100mm?? Damn, that's a mile! no prob . plenty of room in the projector case, y'know.. Attachment 28248

I'm not happy with the 100mm spacing either but its a usable posibility for a good dual at least and a 4mm x 4mm beam with 0.8mrad divergence for the funds invested is also nothing to sneeze at.
Well there are still some people working on this so maybe it can get better. I'm still going to try the 8x cylinder setup as soon as I can.

At this point I'm thinking of maybe knifedging a pair before the cylinders and not expanding the beam quit as much (to maybe 1.2mrad) this times 2 then WP/PBSed to maybe get a quad out of this, has to be tested..

I got the same diode, packaged in the same ordinary bubble foam! I checked with a high-ohm meter and indeed it is not a conducting ESD safe material... you almost feel the electrons getting rubbed free when the diode pins get inserted into it... sigh....

Same for the blue Osram diodes they sell.

This MAY be one way to do it ??? IF the LD can be tamed !!

[kecked]

looks huge. if the distance from the diode to the first lens is to be 100mm that would make this bigger than my entire projector.

ok, the general idea is that the the people testing this only had lava cylinders available, while a 7x or 8x magnification would be more appropriate.
so, to counter this, the distance factor is introduced
with a "proper" set of cyls, the distance should not be 100mm. don't be impatient guys, this is long from over yet

[CDBEAM]

My drawing is just a concept. The distance from knife edge to WP/PBS is shown far to long. I do not have my shorter FL lens ( From Dave ) yet....but I find no difference between 60mm vs 100mm for the divergence. Perhaps with a shorter FL....the 100mm distance would be better ??? Then again...as Mr. Lanek stated......with the higher mag C-Lenses.....things are likely to change again. Fun with Optics !!!

CDBEAM, assuming you could get bigger lenses, you could put just one pair after the PBS, yes?

100mm vs. lugging around a large-frame ion. Hmm.. decisions, decisions ..
