Abstract
Glass can have a high thermal expansion coefficient when it is made up of SiO, BO, NaO, KO, MgO and AlO; contains a partial crystal; and has a mean linear expansion coefficient not lower than of 125×10Kin a temperature range of 50° C. to 150° C. Using this glass as a substrate for a multilayer film filter can fully reduce temperature fluctuations in the filter properties.
