Cezanne question

[mdala]

Hey guys,

The Cezanne I have didn't come with the glass plate that go on top of the film (the one that is placed on top of the film and on top of the scanner's bed).

Is it safe to use a normal sheet of glass as a replacement? If not, what's the best alternative?

Thanks

I find the clamps very convenient. I would concider sourcing one used (likely difficult) or purchase a new one from screen. The main bed is acrylic so not too hard and easily marred by something hard like glass. Having said that a piece of antialisis might work fine if used with care.

Peter has had to do more creative mods like this. Mine came with spares and all the different bed accessories,

I was lucky,

Hi Bob,

thanks for the tip. I think Screen wants $600 or something like that, so, I'll pass. Can you confirm if the small glass tray has a texture on it? Or is it as smooth and transparent as normal glass? Also, where can I find the antialisis material you mentioned?

Just to make sure we're talking about the same thing, the tray in question is the small one with two handles, on top of the film:

Thank you!

Yes, the sheet you place on top of the negative has an anti-newton texture. A Cezanne tech told me the name of what he thinks is a good replacement. I'll look it up and let you know. You could try anti-glare plastic used for framing, but it's texture might be too coarse. The only way to know would be to try it. It's inexpensive. If you use plain glass, you might get Newton's rings, and you'd have to account for the color of the glass when scanning color materials, and as Bob has mentioned you'd want to be very careful that using it didn't scratch the bed.

The small plastic tray goes across the bed and is positioned positively by handles.

Can be used to rough align the film on the bed.

$600 eh, that's a bunch, I don't want to say how many I have, but I use them to load the platen for batch processing.

Since you have one (clamp), you are good to go. Remember this is an XY scanner and you can place your film anywhere on the bed to avoid a blemish on the bed or hold down clamp.

Ooopps,

Wrote antiailisis, meant antinewton,

Can't spell either

Thanks a lot Bob and Peter.

There is something I don't quite understand though. Wouldn't adding another layer of anti newton glass mess up the quality of the scan? I mean, the scanner's bed is already a bit frosted. Sorry of this seems like a silly question.

Would a sheet of high quality anti-newton rings glass do the trick then?

Thanks

You have a lens in there that has an optical rating of around 5400 spi, and an autofocus system that can just nail the proper focal plane.

The system doesnt rely on depth of field to make up for tiny irregularities in manufacture. Is why they cost so much new.

Anyway, frost etc on the lamp side more or less act as a diffuser, especially if not on the film side of the clamp, it's marks , smudges, dirt, etc. on the lens side that ruin the party. Be good to your platen!

The frosting on the platen, if part of the design is welcome (antinewton), but frosting caused by poor cleaning techniques is likely damaging, especially to max spi scans.

Thanks Bob. I'll try to find a supplier for ANR glass then.

That said, if anyone here knows where those Screen trays can be bought for less than $600 a pop, I'm a taker.

Thanks
