Protection Al

Protection Al
  • Durability conforms MIL SPEC specification
  • Customizable

Protection Al is the most common metal film, suit for application of lower requirements. During coating process, we will coat particular material at front surface according to required wavelength region, and coat black epoxy resin material at backside. It suit for all kinds of low power monochromatic or polychromatic optical application.
