Kopp Glass offers over 100 standard glass compositions each designed with a particular set of performance criteria. This list represents just a portion of our standard glass offering. In addition, we can also custom formulate a glass composition to meet your particular requirements.

Glass Number Series: Glass numbers designated with an "X" indicate that a series of compositions are available each closely related, but offering a unique and different feature. These differences may include: thermal expansion, accommodation for thickness, adjustments for spectral transmission, or other.

Designations: FAA (Federal Aviation Administration), ICAO (International Civilian Aviation Organization), AAR (American Association of Railroads, ITE (Institute of Traffic Engineers)
