              In precision optics, microfabrication, and MEMS research, selecting the correct glass wafers is critical for ensuring mechanical stability, optical performance, and process reliability. Two of the most commonly used materials are borosilicate glass wafers and soda-lime glass wafers. While both are forms of silicate glass, their composition, thermal properties, and mechanical characteristics differ significantly, making
