Using our Obducat nanoimprinter, we have developed recipes and procedures to emboss microscale features in several polymers, including PEI (Ultem), PET, PVDF (Kynar), polycarbonate and PMMA (Acrylic). The tool accommodates 6" diameter masters. We have also developed several master fabrication methods including CNC micromachining, laser machining and photolithographic methods.
A polycarbonate microchannel plate embossed using a micromachined metal master is shown here:
