Hi everyone, Could you suggest me a spacer material for separating two (horizontal) glass plates? The spacer should have a thickness of 100 µm, but more importantly, the thickness tolerance should be as low as possible. Also, the spacer needs to be fixed manually on the glass plate: it cannot be processed on the glass plate but it has to be attached afterwards. I thought of using a thin metal sheet and then glue it to the glass plate, but I dont know if it will be the best way. Any help or ideas are welcome!
