Custom-made Ceramic

Infrared Transmitting Glass

Transmission of infrared (IR) wavelengths is an important property for applications such as vision systems, spectroscopy and defense-related uses. Depending on the wavelengths being used, a number of glass materials can be considered.

Some examples of infrared transmitting glasses!

Infrared grade quartz is a special type of quartz with particularly low hydroxyl [OH] content (sometimes referred to as “water free” quartz). This allows the material to transmit well up to 3500nm in the infra red.

Germanium oxide provides good transmission between 300nm and 5.0µm wavelengths.

Chalcogenide glasses are types of glass that contain a substantial amount of elements in the Chalcogenide element group (sulfur, selenium or tellurium). These types of glasses can provide good transmission between the 4.0µm and 14.0µm wavelengths.

Characteristics of infrared transmitting glass include:

  • Excellent transmission of infrared wavelengths
  • Cost-effectiveness
  • Good chemical resistance
  • Good physical properties

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.
