I think its better if you would use a 220mm fresnel to match your triplet

You are certain, but I did not obtain to find one fresnel of lesser focus that 310mm, but I think about not using second fresnel.

They have 220mm fresnels at the Lumenlab store and at 3dlens.com. I think tescorp has some too but I can't find his store

He's in Brazil.
does LL ship there?

Thanks for the tip, but this way we have diyshop.com that it supplies and still I have a friend that vende the lenses, I go to see later if I buy another one exactly fresnel of 220mm, but already I made tests with this of 310mm and gave all certainty, gave a good image.

Hello, and did many tests and will use a lamp dicroica of 250 watts of power, see the video projection of using a dicroica of only 50 watts.
I made two videos using this lamp of 50 watts, and take a look what I found.
