Both metal and dielectric beamsplitter coatings are offered for glass, plastic and fiberoptic components. These films are typically designed for your specific transmission / reflection ratio, wavelength region, polarization, incident angle and incident medium. Low polarization and custom designs are available upon request. Many designs are deposited at low temperature with excellent environmental properties.

Plastic Substrates
ECI offers low temperature coating processes for acrylic, polycarbonate, CR-39 and other polymer optics. Custom designs are available to meet your exact spectral specifications.
