UK supplier of anti-newton ring glass

[Patrick Dixon]

Anybody sourced any in the UK? I know there's Doug at Better Scanning in the US, but it seems a bit silly to be shipping glass 4,000 miles and paying the PO for the privilege of pushing paper on your behalf.

Hi Patrick,

There was a thread about this in Dec last year, it can be viewed here: viewtopic.php?f=3&t=1410&start=0 although there appears to be no resolve.

There's a company called Knight Optical who do it - http://www.knightoptical.co.uk/acatalog ... nGlass.htm

My local glazing company on the Island make a 'lightly frosted' glass. I bought some cut to size for about £5 when I had a 4990 a few years ago. It worked pretty well, I found that it added a very, very slight texture to pale/light (ie sky) areas where the texture of the glass could be seen through the tranny.

I'm sure there'll be a zillion other posts with other solutions also

Knight Optical may be able to help, they are based in Kent.

Ahh thanks. Yes Knight Optical were the only people to come up on google too.

I see they do various standard sizes. What size would fit the BetterScanning sheet film holder? I could make enquiries as to the cost each and of ordering say 10 of them for the group?

I'd be interested - I want to use it with a 4990, taping the film to the underside and using stick-on spacers to raise the film above the scanner glass. I was thinking A4, Letter or 10x8-ish, but size isn't that critical.

A sheet of AN glass 240 x 170mm will fit the Betterscanning mounting station.

Regarding AN glass - I thought I'd be a Yorkshire cheapskate and see what alternatives I could source. I was buying some mountboard from my local Hobbycraft store and noticed they had non-reflective glass/backboards in their picture framing bit. So I made up some height adjuster test shims made out of post-its (good for height experimentation) with some curly 120 roll film taped to the bottom of the non-reflective glass (emulsion side down/film base on non reflective side of glass) a la betterlight holder. There is enough fine texture to stop Newtons rings and I didnt notice any obvious hot/cold spots in the resulting scan. I replaced the post-its with some sticky-back craft foam (same thickness!!) from the same craft store. Total price for a 5*7 sheet less than a tenner. For the odd few times I've used it it seems fine tho YMMV.

regards Tim...

PS I know my local (now defunct) picture framer had some much more expensive etched non-reflective glass which would do the same trick - worth investigating maybe !!

Thanks Tim, I will give the non-reflective glass ago before 'digging deep'.
