IRD Glass

BOROFLOAT® 33 is a high quality borosilicate glass with outstanding properties for a wide-range of applications.

This unique special float glass is manufactured by SCHOTT Technical Glass Solutions GmbH using the Microfloat process and the latest technology. This technology also results in a homogeneous material that has an excellent mirror-like surface, a high degree of flatness and an outstanding optical quality.

BOROFLOAT® 33 is a clear and transparent colourless glass. Its excellent transmission and its very weak fluorescence intensities over the entire light spectrum make BOROFLOAT® 33 ideal for a wide range of applications in optics, optoelectronics, photonics and analytical equipment.

Its low thermal expansion, its high thermal shock resistance and its ability to withstand temperatures up to 450°C for long periods make
BOROFLOAT® 33 a good choice for applications which call for good temperature stability (e.g. internal panels in pyrolytic self-cleaning ovens and over plates for high-power floodlights).

BOROFLOAT® 33 is highly resistant to attack by water, strong acids, alkalis as well as organic substances. Therefore it is particularly suitable for
applications in the chemical industry such as sight glasses for reaction vessels and fittings.

Another interesting field of application is in medical and analytical technology. Measurements are hardly influenced by the glass receptacle because
the exposure to water and acids results only in the leaching out of small amounts of ions from the glass.

BOROFLOAT® 33 has a lower density than soda lime float glass. It makes it possible to construct lightweight laminated glass systems (e.g. bulletproof glass).

BOROFLOAT® 33 has proven itself in many traditional applications and, today, there is an increasing area of usage in new and technically
sophisticated special glass applications such as biotechnology, microelectronics and photovoltaics.
