Optical Cast Plastic Color Filters have excellent thermal resistance. Traditionally, the limitations of plastic materials have made them unsuitable for demanding optical applications. However, advancement in plastic technology has produced filters with properties that can satisfy a variety of optical and environmental needs—and at half the weight of glass. Optical Cast Plastic Color Filters are ideal for use as environmental displays and filters. These filters, with their Thermoset ADC substrate, are also available in custom sizes, shapes, colors, and styles for qualified high volume OEM applications.
