p.1 #1 · Cover glass replacement on Sony A7CR, for M lenses.
I want a company to remove the factory IR/hot-mirror stack and replace with a single thin, high-quality fused-silica window with AR coating (keeps protection and correct flange distance but reduces additional layers). This seems to be the recommended approach (please correct me if I’m wrong about this).
These are the three companies that can carry this out in Germany: IRreCams, Augsburg, Germany; FRAMOS, Munich, Germany; and, Eureca Messtechnik, Karlsruhe, Germany.
Does anyone have any experience with any of these companies? I was told that IRrCams is the friendliest with individual customers. All three companies are reputable and are supposed to be good, but that Eureca Messtechnik, is narrowly, the most rigorous.
Any experience would be most useful.
Any other recommendations for companies that do this in Europe (Not USA).

I had my A7RII modified by Daniel Morrison from https://monochromeimaging.com/ who is unfortunately for you based in the USA.
What very few places will actually do is remove *all* glass in front of the microlenses. The risk is that if there is any contamination among the microlenses in the modification process it cannot be cleaned. When Daniel modded my camera I had about 3 little specks which couldn't be cleaned. Very tiny, not the end of the world.
I chose an Astronomik L3 50x50mm filter because it is 1mm thick and Daniel cut it down to size. Colour balance was quite red but could be white balanced out and I preferred the colour response to the stock camera.
If I were to do it again I would go to https://imagingbydesign.com.au/ here in Australia. Wayne did my GFX100S full spectrum conversion and the guy is a wizard who can do almost any modification you can dream of. Highly specialised facility with clean chambers etc.

IRrecams has a store in Augsburg? Are you sure? I couldn't find any information about that anywhere.
