Hello,
had the GT17s (1999 built) here for tests. Time was short, so I tested them only with water. 20% curve!

wow noos you are a real lens fetisj  , just kidding it is nice to see someone put so much effort in testing these lenses with different amounts of glycol water and curvatures although i am quite happy with my hd10gt17 and am not planning to change those anytime soon, unless i have some money for some nice hfq900s and maybe after reading these posts the hrq900 for a curved screen, who knows.

Hello Dennis,
I think thats the point (and yes, I am addicted to lenses). I think will never have HRQs[ ] here for tests, but I know their specs. So you get with water in the chamber at least very close to the HRQs when using other lenses from the HD10 series (talking about curve).
Best regards
Marc

HD10r5m:
20% with Glycol, 40% (!!!) with water. I think I have found what I was looking for (max curve). I have not found much data on these Lenses, so I would appreciate any data. Thats what I found:
The HD10R5M lens is designed for improved resolution utilizing a curved 4 meter
diameter screen application. It is designed for magnifications of 15-70X. This
lens is designed for Simulation applications and thus was designed for a domed
screen.
Improved resolution, does that mean 12 lines? Well, found the GT17 much sharper (overall and corners). So if you do not need more than 10% curve with glycol or 20% with water, stay with the GT17! But I have to test the H10r5m on bigger screens(now 2,7m).
And please recognize that it says 4m diameter not radius! I have checked some dome screen manufactures. They always speak about diameter, nor radius like when it is about curve screens:
http://www.virtualsimulationsystems.com/media/VSS_Dome_brochure_03Apr11.pdf
I mention that because I would like to know how the HRQs (904/910) behave. Their radius data is smaller(radiusx2=diameter):
HRQ 904
Screen width up to 4 m / 13 ft.
Screen radius 2.5-5m / 8-16 ft.
HRQ 910
Screen width up to 10 m / 32 ft.
Screen radius 5-15m / 16-49 ft.
They are def. 12 lines, but can they do as much curve as HD10r5m? If someone has them, please test them with a white sheet of paper. Turn you corner focus to maximum inside the room, and the measure at what distance of the screen the paper shows a sharp picture (in the edges of the screen).
Best regards
Marc

And what happens when you use an AC lens with an LC system or vice versa. The result will be a "dome application" am I correct?

...I will test this, but I do not think so.
