Hello there,
I really enjoy reading this forum.
After playing around with OHP, I decided to start doing something more.
---
Where can you buy triplet lens? Searched all around, but found only fresnel lenses.
I can take out triplet lens from OHP, but it is 60mm in diameters. Don't know if its ok, but anyway, I have to buy fresnel lenses and it would be great if I also could get triplet lens in that order.
Thanks.

hmm, other question,
Groove pitch for fresnel lenses, smaller is better?
I seen 0,5 pitch, 0,3 pitch and 0,2 pitch, which is better?
