Borosilicate has excellent transmission over the visible and NIR wavelengths working from 310nm to 2700nm. The surface quality is not as high as the BK7 versions.

Low-expansion Borosilicate (LEGB) Windows are very useful as windows in many harsh applications because borosilicate glass has excellent chemical and thermal-shock resistance and has a maximum working temperature of 500° C so are excellent for use in high powered light source applications or an excellent choice for cold and hot mirror substrates.
Borosilicate windows can also be a good substrate for optical flats as it has low expansion properties and therefore maintains its flatness in different environmental conditions.
High temperature load capacity:
- up to 550° C permanent load
- up to 600° C temporarily (< 10h)
Low thermal coefficient of expansion
Thermal coefficient matches silicon
(anodic bonding)
High thermal shock resistance
Clear, practically colorless appearance
Low fluorescence
High UV-Transmission
High chemical resistance against acids,
Bases and organic substances
Low alkali content in the glass composition
Low specific weight
