POROUS GLASS, METHOD OF MANUFACTURING THE SAME AND OPTICAL ELEMENT |
摘要 |
This invention provides a porous glass with a varied porous structure that shows an excellent optical performance. A method of manufacturing a porous glass comprising: a first step of forming a surface layer containing a boron compound and an alkali metal compound as main ingredients on a matrix glass containing a silicon oxide, a boron oxide and an alkali metal oxide; a second step of heat treatment the matrix glass and the surface layer for phase separation to form a phase-separated glass; and a third step of acid treatment the phase-separated glass to form the porous glass having pores.
