Hello,
we are looking for the way to etch two concentric square cavities in
borosilicate glass slides 25x 75x 0.5 mm. Close to the surface is a cavity
22x22mm 110+/-10um deep and second cavity is 16X16 mm and 67+/- 20 um deep.
Minimal roughness on the bottom of second cavity is required for visible light
detection. It could be done out of 3 pieces of glass, but this way is
expensive. Please, advice
Regards,
