Broken 4x5 protective cover glass

[younghoon Kil]

Hi,
Recently, the protective cover glass of the Maxwell HI-LUX focus screen broke while shipping the Chamonix camera to China.
I sent an email to Mr. Bill Maxwell, but did not receive a reply.

First, I bought protective clear sheet from Chamonix and installed it instead.
But this is plastic, not glass.
Mr Hugo said Chamonix now uses plastic clear sheet instead of glass sheet to cover the Fresnel lens.

Anyway, I want to get a clear sheet made of glass.
If there is a seller, please let me know.
Thanks.

I suggest that you call Bill Maxwell if at all possible.

On the picture you posted, I can see it is only a corner that broke off.

There is a special glue for restoring glass, which is even used in archaeological musea for restorations, that is extremely fine and when dry is hardly visible, years ago I used that, I think it came from AkzoNobel, for repairing the ground glass of my 13x18cm Sinar Norma, which worked perfectly...

This protective glass is not a special glass, just a piece of glass to protect the fresnel glass. You can go to any window glass stores near you and they will find a piece of matched glass for you, cut the size you want. I have done that before when a seller did not ship the protective glass with the camera to me. It only costs about $6.

Why do you object to plastic? Glass could only break again.

I'm just looking at your photo again. Is that the protective cover that broke or the ground glass?

Thanks for all the replies.

1. I emailed Bill Maxwell again. my English speaking is very bad.
2. The broken protective clear sheet was discarded in China.
3. Following your advice, I am looking for 1~1.5mm thick clear glass here in South Korea.
4. For some reasons I need glass instead of plastic.
5. "Ground glass + fresnel lens" is not broken, protective cover is broken.

If it's just a piece of glass, buy a cheap clip photo frame to have the material and cut it to size.
A common size is 6x4" but if the cut is tight go for a larger one (10x8"). This glass is thin and very easy to cut; or just give it to a glass store and ask for a cut.
Smooth the edges with sandpaper if needed.

I bought an 8x10 camera that had plastic over the ground glass to protect it. I started having a had time focusing with the camera, so I resolved to clean the ground glass and noticed the plastic had developed some sort of fade/fogging that was uncleanable. I threw away the plastic and resolved to just be careful with the ground glass. (Adding another piece of glass is fine, but in an 8x10 that's much more extra weight)
