OPTICAL GLASS TESTING

AGI has a complete testing facility to ensure our optical glass blanks adhere to the high standards we set for ourselves. We operate in conformance with MIL-G-174, MIL-l-45208 and MlL-Q-9858. All materials are accompanied by a certificate of compliance. Melt data, test reports and measured refractive index values are available on request.
