SCHOTT’s expertise and reputation for the highest quality materials is demonstrated with 8337B. This borosilicate glass offers outstanding physical properties that provides it with high UV transmittance and low thermal expansion. This makes it ideal for use as housing for UV light sensors.

Unique properties for specialist applications

Exceptional UV transmittance

Of all SCHOTT products, 8337B offers one of the highest transmissions in the deep UV range. For UV light transmittance, those credentials are hard to beat.

Matched thermal expansion

SCHOTT 8337B forms a direct bond with tungsten and the iron-nickel-cobalt alloy Kovar, as both have similarly low thermal expansion coefficients.

Low transformation temperature

Standard glass blowing burner technology offers facile 3D hot forming of 8337B glass tubing.

Impressive impermeability

Tungsten or Kovar-sealed 8337B envelopes provide devices with a long lifetime thanks to the unique properties of the glass and its high geometrical accuracy.

Physical Data

SCHOTT 8337B borosilicate glass is used for UV-transmitting photomultipliers and UV detectors. It can be sealed to KOVAR metal and tungsten, and is highly UV-transmitting.
