Well...there are several sources for both Anamorphic prism's and Cylinderical Lenses. The real question is..." How do ya mount them on the business end of a pointer " ??
http://laserpointerforums.com/f49/a...any-hand-held-unit-proto-type-done-89122.html ...is one way to go !
Do we have a real interest ???? MMmmmm ??? Real = 25~50 units.....in my book !! Maybe we can get DTR to carry the EZ units ????????????????????
I would speculate that the 3.5W 445nm and the 1W 520nm can both be fairly corrected with A-prism's....but the P-73 638nm still demands Cylinderical lenses !! It also appears that "Tomorrow Systems" uses Anamorphic Prism's to correct the 3.5W blue....per their website...and it is a very nice website...a bit pricy though, but then, these are TEC stabilized Lab units, likely for extended duty cycle's used in the projector world. Also, I think "Tomorrow Systems" are in Poland...if I did my homework correctly.
Group thoughts ?????
Correct! I'm from poland (together with friends).
Here is the hello thread:

But incorrect that I'm using prisms - I'm using cylindrical lens pairs.
The prices will change a little because we are editing the site all the time, additionally LPF will have some discounts but I will write in in sales thread after I fulfill all the regulamin requirements
I'm using cylindrical lens inside my modules, not prisms. I designed them myself and I ordered around 400 pieces of this cylindrial lens pair.
One type is for 638nm and one is for 520nm and 445nm. They work amazingly and power drop is nearly visible.
Soon I will have my own mill, so it will be easy to make some lens frames and mounts, since cylindrical lens are not that easily mounted.
corrective optics? my ears are pricked up!
Here are the photos of the 4W 445nm modules. It has 3,5A current set (not overclocked) and with good cooling the power (after all lens) is 4,2 - 4,3W, without cooling it drops to around 3,8W quite fast. But for sure when you use 5A you will get around 5,5 W ;D Here is the photo inside for you quys.
I also attach beam spot shots.
M140 shots are WITHOUT beam correction.
NDB7A75 WITH beam correction.
Sorry I do not have NDB7A75 without correction but it is similar to Mitsubishi and Oclaro, around 50mm.
As you can see, NDB7A75 with correction is even better than M140 without. So imagine that your M140 had 5W power
