Fused silica is the amorphous (glassy) state of silicon oxide (quartz, silica). It is a typical glass with a long-range disordered atomic structure. It provides its high service temperature and low coefficient of thermal expansion by cross-linking its thr

Zinc sulfide (ZnS) is a broad-band (3.72 eV) group II-VI semiconductor material with high optical transmittance in the near-infrared (1-3 μm), mid-infrared (3-5 μm), far-infrared (8-12 μm) and other spectral bands, with moderate mechanical properties, the

Sapphire is a single crystal material that has excellent light transmission properties and can work in the visible and infrared light ranges. It has high hardness, high corrosion resistance, high heat resistance and good mechanical strength. It has a good

Optical glass domes are essential components that are widely used in underwater detection equipment. They are made of optical glass, which is known for its superior optical properties, such as high transparency, refractive index, and low dispersion. These
