Glass is manufactured from silica oxide, a hueless crystalline compound found as quartz, flint, or sand. In machining quartz glass, the 99.9% exceptionally pure silica oxide is melted and cooled to the desired shape. Jewelry and gemstones. Quartz has a broad color range, making it ideal for jewelry. It is also readily available and highly durable.
3.1 Precision Grinding of Microlens Array. In this study, two types of new designs are proposed as the surface of the glass substrate is plane and macro-freeform curved, while well-determined microlens array is fabricated on the surfaces. Here, micro-grinding is employed to reach the micron-scale forming accuracy.
