optical glass materials

Lens are made of optical glass and should be cleaned with cloth made of special materials.

镜头都是由光学玻璃制成的，要用特殊材质的镜布来擦。

Diamond grinding wheels are widely used as grinding tools in manufacturing of hard and brittle materials, such as hard alloy, engineering ceramics, optical glass, semiconductor materials, and granite.

金刚石砂轮广泛用作硬质合金、工程陶瓷、光学玻璃、半导体材料、花岗岩等硬脆难加工材料的磨削工具。

The optical microscope and SEM were employed to analyze the damage of glass fiber during weaving and resin permeability in the course of molding of composite materials.

同时采用光学显微镜和SEM分别对织造中玻纤断裂情况和树脂在复合材料成型过程中的渗透性进行了研究。
