Optically clear ceramic for sealing mirror-finish substrate

Sorry but looked and even with in depth searching I can only find this !

It looks you are trying something you need to patent when you figure out how to do it Sandyc!

Good luck.

P&T can do this In Redding CA www.ptfrpcustoms.com or 530 2217335 talk to Phil

Hi,

look at spie.org and search for the conference proceedings on sol-gel-optics.

I suspect that shrincage at curing will distort everything.

If you think about producing replicas then go to the people that make the radar to infrared to x-ray mirrors replicated from ultraprecision machined parts.

In the US Itek should know, Lawrence Livermore provided the technology, in France ask Reosc, in Germany the Zeiss people know this.

Replica optics is also found in SPIE large database of proceedings and articles, OSA will have some too.

I would guess that once you have your ceramic "glass", you would then need to coat the silver back ground as I do not see it coming through any other ceramic process with such high temperatures that are usually needed....

This will also allow the surfaces of the glass to be polished first, which I would guess would also be needed after firing was done.....

These companies perform silica coaating:

Do a google search under "mirror coatings". You will find companies such as Spectrum Coatings in Deltona FL. They can supply a variety of oxide coatings including SiO2 (Quartz). There are also a variety of organic coatings that will be lower cost, but not as durable.
