Filtron Edge or Long Wavelength Pass Filters block light from the Ultraviolet to any of the 13 wavelengths from 400 nanometers (nm) to 800 nanometers. Our Edge or Long Wavelength Pass Filters, also simply referred to as Filtron’s E Series materials, are perfect light management solutions compared to glass, which is typically more expensive, does not machine or mold easily, and sheet size can be restrictive or prohibitive. The Edge Filters are available in resin form for molding, in standard 24″ x 36″ acrylic sheets, 6″ x 6″ polycarbonate plates, or custom sizes.
