Hi all, have been reading lots of info here and will be starting to build my own PJ in June
Afer reading many posts and different opinions, I am after some frensel lenses that will suit a 17"Lcd
monitor (not widescreen).
Do I need a 220 and 330 or 2 330 or something else

Thanks

What triplet will you use?

Hi, will prob use the pro lens kit unless you can recommend something else

Thanks

If you buy the LL pro kit when it's back in stock the you will get a 220mm and a 650 mm fl fresnels matched to the pro triplet.

Thanks for that, I thought that the 650fl was for the widescreen??

Each triplet has a fresnel that matches it. The pro lens is 500mm FL and the fresnel that go with it is 610mm ( the number 650mm is wrong)

A 450mm fl triplet goes with a 550mm fresnel and a 327mm triplet goes with a 327mm triplet.

The rear fresnel can be a 220mm or 330m. If you want to go to a 330mm and a condenser lens then the 330mm must be larger than the one LL sells so you will need to get it from ebay or 3d lens.com

A condenser system is brighter. You need use a lamp with a shorter arc than the LL lamp for a condense system.

The S400DD or a HQI 250 or a lot of 250 watt lamps are good fr a condenser system.

Thank you for that information

Regards
