wrong axis - you'd get a 10mm x 4mm if i'm not mistaken

What solution ? We were just trying to set up a group buy for the diodes...

My set up is off line for now...while I fabricate a better Lava lens holder and incorporate a P3 driver....BUT.....I got a 1.1mRad ( Max) with an aperature of 1.5 x 4.5 mm with the Lava lenses....with a 406-G-1 colliminator. I will measure again...when things are back together.

wow!
I would have loved to stop by and seen that...

Can someone try this 3 prism setup with the red diode?

It gave me low loses with the blue diode due to the more "conservative" angles that the prisms are set, around 3,5% more than just a single prism.
It also gave me a very nice rounded square spot of 14 x 14 mm at 13m distance (405-g-2 collimator)
Maybe it works with the red too.

I see it as a way to achieve higher magnification ratios using anamorphic prisms, or to have less loses with lower magnification

So, has anyone got a pair to send me?

Of course I will pay for them.

andy, you can try user DTR here, or get them from ebay http://www.ebay.com/itm/Mitsubishi-6...item27bde708ab

Thanks, I will get some in.

Corrected with a 5x cylinder telescope the aperture will be about 2.5mm x 4mm with a divergence of about < 1-1.2mrad.

thats really not that bad, figure a 1W 635nm CNI has a 5mm x 8mm beam

Does anybody know where to get good cheap prisms with a decent ar coating for these 638s ?
