Embodiment Construction

[0039] After extensive and in-depth research on various glass compositions and the influence of different components on each other, unique glass compositions have been discovered and invented, which can meet the requirements of the above-mentioned application fields and the methods to solve the problems, respectively, as follows.

[0040] In the research and experiment process of glass composition, each designed formula is composed of about 200 to 250 grams of glass. After weighing and mixing thoroughly, the material is added to the platinum crucible and placed at high temperature. In the electric furnace, the melting temperature ranges from 1350°C to 1460°C. According to the temperature requirements of different glass compositions, after the melting time is about 90 minutes, manually use a platinum stirring rod to fully stir it for about 5-10 minutes, and then let it stand for 20 minutes. Think of it as a clarification.

[0041] As mentioned above, changes in the composition of t...

Said glass composition contains (mole%) 36-66% of silicon dioxide, 0-12% of aluminium oxide, 0-6% of boric oxide, 0-10% of magnesium oxide, 0-16% of calcium oxide, 0-16% of strontium oxide, 0-16% of baria, 0-8% of zinc oxide, 0-32% of lithium oxide, 0-25% of sodium oxide, 0-25% of potassium oxide, 0-20% of cesium oxide, 0-6% of phosphorus pentoxide, 0-8% of scandium oxide and others.

Description

Technical field [0001] The present invention relates to glass suitable for making substrates of different thicknesses and flat plates, and a film of suitable material is plated on the substrate to be used as an interference filter. More specifically, the relevant glass composition of the present invention can be designed according to the thermal expansion coefficient requirements of different coatings, and the ratio of the glass composition composition can be adjusted so that it has the required thermal expansion coefficient while achieving high thermal expansion coefficient control. In this way, an interference filter whose wavelength band of light waves does not move due to changes in environmental temperature and stress can be produced. Background technique [0002] The production of interference filter is to plate one or more dielectric layers or conductive films on a thin and flat glass substrate, and each film thickness is a composite layer of λ / 4 (1 / 4 of a specific wavelen...
