Borosilicate glass 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 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 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 has excellent chemical andthermal-shockresistanceand 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.
