Can anyone tell me what the distance is from an Orc 1000B lamphouse to the aperture plate? I've checked the manual but it doesn't seem to mention it, unless of course I missed it.

If you are asking what I think you are, just place the snoot on the lamp up against the rear of the projector. That usually work for me.

I've used this lamphouse on 3 different projectors. I've also found the best distance is right up against the projector.

Most all of the early ORC brown & cream colored lamphouses had a working distance of 7 1/2 - 8 inches from the front bulkhead (Not the lens cone) to the film aperture..This applies to the X-16. X-35, M-1000, X16S, 1600, 2500 series lamphouses.

From my M1000 manual:
Don't forget the Beam Spreader for 35mm. I've seen these lamphouses on 70mm projectors but have no idea of how well the aperture frame is lit or what is the working distance.

Thanks for your help guys, and thanks for posting that scan Phil.
I have mounted, what the manual calls, the 'negative lens' with the concave side facing outward. Would this be correct?
Posted by Phil Hill (Member # 371) on 02-14-2006, 04:42 PM:
The flat surface of the lens should face the screen; the concave surface toward the lamp.
Same with the Strong Super Lume X.
BTW: Make sure there are no fingerprints or oil contamination on the lens, it will crack pronto.

Phil that should be strong Lumex not the super lumex
Posted by Phil Hill (Member # 371) on 02-14-2006, 07:18 PM:
You sure about that, Gordie? I have no experience with the Lume-X, only the Super Lume-X and I've always used the Beam Spreader lens for 70mm...and the heat filter for 35mm.

The beam spreader for 70 I use but I thought you were refering to 35mm use like the M1000
Posted by Phil Hill (Member # 371) on 02-14-2006, 08:57 PM:
You're right, my post was confusing. For clarification:
M1000 16mm: Nothing or a (Dichroic) heat filter to help block IR.
M1000 35mm: Beam Spreader (Negative Lens). Flat surface towards screen.
M1000 70mm: Ain't got no clue! ![[Smile]](smile.gif)
Super Lume-X 35mm: Nothing or a (Dichroic) heat filter to help block IR.
Super Lume-X 70mm: Beam Spreader. Flat surface towards screen.
