Custom-made Ceramic

Filter Glass

A wide array of filter glass material is available with many differing properties. In most cases the filter glass is acting to restrict transmission to particular wavelengths either in the visible region or other regions such as infrared. The filter either selectively transmits desired wavelengths or else blocks undesired wavelengths to achieve the required result. In some cases a number of filter glasses may be used in combination. The glass may be colored, or not, depending on the application.

To determine which filter is most appropriate we need to know which wavelengths need to be transmitted, or blocked, along with details of any special operating conditions such as high temperatures.

Characteristics of filter glass include:

  • Can allow selective transmission of particular wavelengths
  • Can be used to block undesired wavelengths
  • Good chemical resistance
  • Can be thermally toughened if required

Goodfellow Ceramic and Glass Division is able to supply a wide range of ceramic and glass materials as finished components. Our capabilities range from custom-made precision microcomponents with very high tolerance features to large heavy-duty components used in industrial applications. Additionally, standard semi-finished forms such as tubes, rods, bars, plates, crucibles and spheres are often available from our wide inventory. Please contact us with full details of your requirements, including drawings where available, and we will review and respond with a quotation as soon as possible.
