I had a 17 inch all non pro setup but after using it for a few years i cracked a lens and finally my father chipped the triplet so i need all new stuff, I cant use the standard lenses as there 2 small, but I had mine cut by someone and I don't want to risk cutting again.

so can i use the pro lenses with a non pro triplet? side effects?

I would buy the pro triplet if it were say $60 but $200 is steep

also anyone know if you will be able to buy that luxim bulb someday?

thanks,

Bugmage

the collimating fresnel doesn't matter. most people go for 330 or 220 depending on how much vignetting you can stand.

the collector and triplet MUST match (roughly: a 500mm triplet can work with 550 or 650mm collectors).

they're.

Just buy a new standard triplet here and the 220mm Pro fresnel from the LumenLab Store.

Then buy a 330mm large fresnel from www.3dlens.com , part # A395a

I haven't been on LL in a while so let me make sure I have this right,
collimating fresnel is the one that bends light towards lcd, the front fresnel and the triplet have to match...

so ill admit it im getting a little lost via the working, rear fresnel, front fresnel, and triplet

hmm
this is what i would buy:
s15 triplet Focal Length: 320mm
650mm Pro Fresnel Lens
and the 220mm Pro Fresnel Lens


simply because i have a 17inch lcd and the others are to small

would this combo work?

alright permission to newb me granted, even though ive already build a projector

No the 650mm fresnel will not work with the standard triplet. You need an oversize 330mm like the one I mentioned above

darn

so know any good places to find a triplet

and let me get this right, so if i use a 650mm front lens then the triplet has to be 650mm or +-50ish?


thanks

oh i missed this post thanks guy!

The fresnels have to get light to the triplet. The triplet has to be positioned such that it focuses the LCD to the screen.

For all practical intents and purposes, you cannot use the pro fresnels with the standard triplet. It can be done, but you have to do some pretty stupid things to make it work, and it's better to just get the apropriate fresnels.

Also, for what it's worth, I know that this question is answered in the FAQ.

Last, but certainly not least, I strongly recommend that you figure out EXACTLY what you're getting into using a larger panel with the standard lens.

1. Use the focal calculator to figure out what the throw will be.

2. Use masking tape to mark out a "screen" on your wall the size that the focal calc says that it will me.

3. Get a cardboard box, at least 2 cubic feet. Place it the specified distance from this "screen" -- place it so that it is dead center to the screen. The larger the panel, the less keystone correction that you will have.

4. Try to find a place to sit where you can see the whole screen comfortably, around the box (and whatever you needed to hoist it to the appropriate height)

Assume that you cannot move that box more than 6" in any direction. I think you'll come to realise why the pro lens is worth the money.
