I have a Stewart OptaWave 120 and a single mirror OptaMirror system with a Electrohome ECP 4501. I bought it all at a storage space auction and most of it is still in the original crates. There don't seem to be any manuals so I am looking for any info on what it might take to set it up. From what I know it appears that it will take about 5 feet behind the screen. If any one has any experience with this screen anything would be helpful. Also any ideas on where to get some manuals. I've already piked up some real good advice on projector maintenance from this board.
Wow..! I don't know what you paid but you received some very top professional Fortune 500 type Boardroom equipment there.
The Optawave screen is a lens type rear projection screen. It has a lenticular lens on the viewing side and a fresnel lens on the projector side of the screen. The light calumniating fresnel lens, was cut in Stewart's Ohio factory on one of the World's largest optical lathe. The lathe has a capacity to cut a 12 foot diameter fresnel lens. Let me tell you that you can smoke a few red ants or other small animals in the company parking lot with one of these lenses!
Anyway... The W.A.V.E. part of Optawave stands for: "Wide Angle Viewing Envelope" as the lenticular lens has a Half Gain out past 52 degrees allowing every seat in the house a very bright image. The Optawave will maximize the image Foot lamberts and is a perfect match for the Electrohome. The Mirror is a first surface optical glass mirror and comes with towers to hold the mirror frame in place around 6 or 7 feet of the floor. The Optakong mirror system also comes with a projector stand platform made to fit the electrohome projector. The MSRP, if bought today, would be over $14,000 for the screen and Optakong system.
If you can find the serial number off the outside of the crates it is very likely we have the original CAD details in our archives. We might be able to fax you a drawing of the set up geometry for the rear projection system.
Call 800 762-4999. Ask for Greg Van Arsdale. He is one of our top engineers. Also...be sure to explain to him your circumstances in detail as this will give him a better chance of finding the info you seek.
I hope this helps.
Regards and Good Luck,
