API offers a wide range of acrylic and glass filters already cut to size. Linear polarizers, circular polarizers, quarter wave retarders, and half wave retarders are available in numerous pre-cut sizes. For linear and circular polarizing filters, we offer 38% and 42% transmissions. Our glass filters are supplied with HEA broad band anti-reflective (BBAR) coatings on both sides.
If you do not see a size or shape you require, we can easily make it using our in-house laser and waterjet capabilities.
