Author Topic: Orc 1000B distance from aperture? Matthew Taylor Expert Film Handler Posts: 186 From: Essex, UK Registered: Mar 2004 posted 02-13-2006 02:50 PM                     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.  |  IP: Logged Don Furr Jedi Master Film Handler Posts: 509 From: Sun City, Ca USA Registered: Nov 2002 posted 02-13-2006 03:42 PM                     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 also found the best distance is right up against the projector.  |  IP: Logged John Eickhof Jedi Master Film Handler Posts: 588 From: Wendell, ID USA Registered: Jan 2000 posted 02-14-2006 12:56 PM                        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.  |  IP: Logged Phil Hill I love my cootie bug Posts: 7595 From: Hollywood, CA USA Registered: Mar 2000 posted 02-14-2006 03:36 PM                  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.  |  IP: Logged Matthew Taylor Expert Film Handler Posts: 186 From: Essex, UK Registered: Mar 2004 posted 02-14-2006 04:23 PM                     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?  |  IP: Logged Phil Hill I love my cootie bug Posts: 7595 From: Hollywood, CA USA Registered: Mar 2000 posted 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.  |  IP: Logged Gordon McLeod Film God Posts: 9532 From: Toronto Ontario Canada Registered: Jun 99 posted 02-14-2006 07:05 PM                     Phil that should be strong Lumex not the super lumex  |  IP: Logged Phil Hill I love my cootie bug Posts: 7595 From: Hollywood, CA USA Registered: Mar 2000 posted 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.  |  IP: Logged Gordon McLeod Film God Posts: 9532 From: Toronto Ontario Canada Registered: Jun 99 posted 02-14-2006 08:47 PM                     The beam spreader for 70 I use but I thought you were refering to 35mm use like the M1000  |  IP: Logged Phil Hill I love my cootie bug Posts: 7595 From: Hollywood, CA USA Registered: Mar 2000 posted 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! Super Lume-X 35mm: Nothing or a (Dichroic) heat filter to help block IR. Super Lume-X 70mm: Beam Spreader. Flat surface towards screen.  |  IP: Logged System Notices Forum Watchdog / Soup Nazi Posts: 215 Registered: Apr 2004 posted 05-30-2007 02:23 PM                 It has been 469 days since the last post.  |  IP: Logged Gordon Burke Film Handler Posts: 15 From: San Jose, CA Registered: Sep 2005 posted 05-30-2007 02:23 PM                        quote: Phil Hill M1000 35mm: Beam Spreader (Negative Lens). Flat surface towards screen. The manual available on Film-Tech shows the curved surface toward the screen and the flat toward the lamp. Is there something in the drawing that is backwards? Can someone verify?  |  IP: Logged
