Glass-to-Metal Seal Colors

To differentiate similar products and to identify certain connections (e.g. polarity identification for customer processing), various colors can be added into the glass-to-metal seal. The coloring does not alter the properties of the glass, except for filter glasses sealed in TO caps. In this case, the coloring determines the optical characteristics of the glass. Another exception is glass seals for applications in opto-electronics. In this case, light transmission of the glass can be considerably reduced by coloring.

Available colors for glass-to-metal seals include:
  • Green
  • Blue
  • Brown
  • Black
  • Neutral glasses
