Polymethylmethacrylate resist commonly used in MEMS characterization.
Acronym for PolyMethylMethAcrylate, a mask used in the LIGA process.
Acronym for polymethylmethacrylate. Original material used in the manufacture of “hard” contact lenses. In today's rigid contact lenses, PMMA is often used in combination with other polymers to increase the oxygen permeability and allow longer wearing times.
a lightweight, crystal-clear, glasslike polymer used in airplane windows, taillight lenses, and light fixtures
acronym for polymethylmethacrylate. A clear polymer used in Intacs®. Used since 1952 in intraocular lenses related to cataract surgery. See Intacs®.
abbreviation for polymethylmethacrylate.
Polymethylmethacrylate. The old-fashioned rigid clear plastic material that non gas permeable contact lenses were made from.
PolyMethylMethAcrylate (also known as Acrylic), a thermo-plastic material considered for CDs but is rather brittle and the Aluminium layer does not adhere well to its surface.
Old-fashioned hard contacts were made of PMMA, which is not oxygen permeable; today's rigid lenses contain other polymers that allow oxygen to reach your eye.
