2″ Diameter, Uncoated Plastic Acrylic Window

Product Details Highly Scratch-Resistant High Visible Light Transmission Cost-Effective Alternative to Glass Polycarbonate Plastic Windows Also Available Acrylic (PMMA) Plastic Windows are ideal for integration into lightweight optical systems. Compared to polycarbonate windows, acrylic windows are more scratch resistant and can be polished to restore optical quality but are more likely to chip or shatter. Acrylic (PMMA) Plastic Windows also provide a higher UV light transmission than polycarbonate and are recyclable. Acrylic windows are used in a wide variety of industrial and medical applications including aircraft windows, automobile headlights, and ophthalmological devices.
