Polycarbonate is an excellent plastic for display filters. It provides high impact resistance combined with an excellent flammability rating, unlike acrylic. In terms of clarity, polycarbonate is comparable to glass, but being a much lighter substrate polycarbonate is more suitable for applications where weight is an important consideration.
Optical Filter's polycarbonate sheets are available in a range of thicknesses and surface finishes. Our CNC cutting facility will machine steps, holes with threads and grooves to strict tolerances.
Because polycarbonate is easily scratched due to softness, Optical Filters recommends that polycarbonate filters are specified with a clear hard coating to front surface and preferable to both sides. This coating provides a high level of chemical resistance while eliminating the risk of scratching through general handling of the product.
