Default which Triplet lens to buy?

hi guys,
great informative discussion here, i started building my LCD Projector, just want to know which Triplet lens is perfectly suits the 15" LCD panel? and from where to buy it in India?
i just tried using 150mm plano convex lens but the image has blurred edges only central part is somewhat sharper.

please provide me exact details of Triplet to be used so that entire image will be sharper and there are no edge blur problems.

also suggest any shop from Mumbai from where i could get those triplet lenses if possible?

Thanks

Finally got a Benq 15.6 inch viewable (16inch monitor) monitor for my projector(G610HDA).Over the weekend met Aramosfet, together we went for shopping.It was a nice experience.Bought 250W OSRAM MH and OSRAM Ballast from BV iyenger stree.Then had some discussion with Aramosfet and after that we bought threaded rods,bolts,drilling bits and some hardware tools.
I must say, Aramosfet is a nice guy to work with...very cooperative.

Now that we have a prototype, we are planning to go for the projector design...but this time systematically with all past experiences documented.

Thanks Aramosfet...thanks DIYAUDIO.

Ha Ha Ha..... So many good quality images available in this entire thread....

Ofcourse the image quality will not be like a commercial LCD projector.

Regards,
Bishnu

Guys,

I am from hyderabad. Looking to build a DIY . Did some research and I just finalized a 10" XGA lcd panel from a partsmanfacturer from US and a controller kit from China .

I would be starting the build as soon as i receive them and test them. I would like to hear your experiences and share ur knowledge.

Also I checked with lensel optics reg the fresnels ,they r available. But the triplets are not available. Any ideas about where we can acquire them? I found a triplet in hyd but its 3600+taxes.

I can share my mobile if someone is interested to join. my mail id is gunsreekanth@gmail.com
