I looking for info on a lens made by U.S. precision len.
It is a Delta 42 from a Rear projection tv.
I believe it is a f1.0, but if anyone knows where i can access any info on this lens.
it resembles this Delta 265

Depends on what ur're looking for... I can tell you that it will only work up to like a 5 or 6 inch source, it has to be placed pretty much right against it... It should be about 100-150mm in diameter... Look around 3m.com... ive seen a pdf document with diagrams and info on some deltas, perhaps that one is there too...
