Borosilicate glass 3.3 is one of transparent colorless glass, through wavelength is between 300 nm to 2500 nm, transmissivity is more than 90%. Coefficient of thermal expansion is 3.3. It can acid proof and alkali , the high temperature resistant is about 450°C. If course handling , the high temperature resistant can reach 550°C or so. Apply to lighting fixture , chemical industry , electron, high temperature equipment and so on.

Borosilicate glass 3.3 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.

Borosilicate glass 3.3 has excellent chemical and thermalshock 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.
