Low expansion glass is all about the extreme low thermal expansion properties these types of glass can offer your application. Low expansion materials also often offer lower levels of inclusions, striae and overall internal stress, as well as excellent chemical stability.
These qualities enable low expansion glass to be an optimal material choice for a wide variety of high precision applications, including everything from mirror blanks for large astronomical telescopes and space satellites to wafers used in lithography.
