Lewis that was my first thought but they’re too thin at 1mm.
The exact thickness and refractive index are crucial - to within a few microns. Get that wrong and it will never be the same again.
He suggested 2.5 mm but I wonder how that was determined. The glass in small picture frames is about the only easy source approximating that.
Then there’s the challenge of cutting a piece to the required size without scratches - any scratch will show on every image taken through it, since it’s hard up close to the sensor.
TBH the only real solution is a new camera.
