I currently have a CRT base machine. I can see fant scan lines on 1080I but can not see on 1080P. With that said I can only assume that my scan lines over lap and there's a reduction in rez. I did some testing with a very high end lens.
30% better brightness and better rez but is it worth it.
Anybody do any testing.
Any thoughs.
Best Regards

What Projector and what was the lens you were testing. And there are no anmorphic lenses for crt out there at least that i know of.

It was a sico len's. A rather large one used for Digital Cinema. I currently have a HJT ILA12K unit in may HT. It Has hand picked Cinema ILA's and the smallest dot size fast tubes I could find. I want the next level of proformance and I can custom fit schnider lenses. Any info out there?

This thing is insane! it was 185,000 dollars new !!!!!!!

Did you see the 7-kilowatt bulb? That's what I'm talkin' about! 12000 center lumens... how many foot-lamberts do you think you'd get with a 12 foot screen?

I find it interesting that they spec the contrast of film at 1k:1. They could be fudging to make the 1k:1 of their PJ look better, but it might be true - anybody have any data on that, and whether it's ANSI or on/off?

On topic, I'd (and probably everybody would) love to have anamorphic lenses for my PJ. Huge brightness and resolution increase. Only problem is 16:9 wear pattern but I can fix that in software... :)

Anamorphic lenses would be a huge expense, too bad they were not a option when they first made these CRT PJ's, then they would be available and a hell of a lot cheaper.

The best thing to do is get a first surface mirror and curve it.

You could also cheat, make a 16X10 screen and stretch the image. That would be a 10% increase in lines you could cram in.

At 1080P on a 9" PJ you would gain nothing, as you would just end up with more space between the scan lines. You would have to run a higher resolution then HD to take advantage of being able to use more phosphor. It would be a odd resolution too, as you can really only gain extra usable phosphor on the top and bottom of the tube. I would think people would have the width already maxed out before they even thought of anamorphic lenses.

Deron.

Too bad very major company gave up on crt except for vdc, someone probably would have made a 16.9 tube by now. that be Sweet !

Perisoft, I may be nuts but the monster can light up my 22 foot ciniperf screen with 16 fL. I'm getting around 2000:1 on off CR and yes it can heat my entire HT. You should see the meter spin. the lamp draws about 60 amp single phase.
Deronmoped and nasou66 I did this simple test. get a sony bluray disk go to test easter egg. On the rez test patern there on the very bottom in super small text, the address on the company that made the test pattern. It's legable with an anmorphic. It not a huge improvement but It's there.
The 3:1 lenes are only 2.5" dia so it possible to machine a custom mount using a small 3" or 4" anmorphic.
Any thoughs on testing that would be more conclusive.
My thought is if you can't see scan lines then your not getting full rez.

If you're used to a projector with that light output and your screen size, how will you ever be satisfied with the much lower light output of a CRT projector, even if an anamorphic solution was possible? I'd say your best chance would be to blend several CRT projectors, maybe two rows of either three (12:6) or four (16:6) CRT projectors. Seems like you have the money to do it; go for it!

I think Mr Chase is going with the same projector.
Properly setup they throw a very film like image.

Alan, The ILA12K is a crt projector. It has three inferred CRT's that paint the image on the light value. It has the best of both worlds light from a xenon lamp and rez of crt.
Yes, it is the same projector as Aronld Chase is installing
Anyway. It sounds like no body has played with Anamorphic lenes.
I just want that edge over those Digital guys out there.

Your ILA has the advantage as you pointed out in that its lens are a much smaller diameter then that of your typical CRT.
I bet in your case it could be possible to mount a set of three add-on lens for full raster wide screen. I wish here was something for CRT projectors. I know years ago thee was hi end CRT company that Chris Stephens was working with that was working on such a lens but it sadly never materialized.

Here is one old diy thread.

One Finn tested 2th generation anamorphic prism using two prism design few years ago to his G70. First one was glyserol 24 deg and second one water 30 deg. No chromatic aberration with two prism design like with one water prism above and picture sharpness was about same that without prism. But glyserol was taking all that extra light output that bigger picture in tube was giving, so not worth with glyserol.

Maybe glycol would work better, but he never tested it.

Then here was also one thread about anamorphic mirror system, but if I remember correct that second mirror was almost impossible to build.

Wow, and to think I use to like those old forum colors:(

Thank for the link Ile. I thought I was crazy. I'm thinking of using a Schneider lens. prisms have lots of problems. That's not the way to go.
I'll keep you posted on project.
Best regards
