Sapphire bullet-proof technology is one of the challenging high-tech fields that can offer valuable resources and assistance to police, military, and security agencies. Whether in counter-terrorism, protecting important individuals, or safeguarding crucial national infrastructure, sapphire bulletproof technology plays an irreplaceable and significant role.

Quartz glass lenses are extensively used in optical imaging applications due to their advantageous characteristics, which render them ideal for producing high-quality images. Below are several applications of quartz glass lenses within the realm of optical imaging.

Although certain studies indicate that blue light may have an impact on ocular health, there is currently no definitive scientific evidence substantiating the claim that blue light filtering lenses can prevent or treat eye diseases. Nevertheless, individuals who engage in prolonged use of electronic devices or those with pre-existing ocular conditions may still derive...

The infrared cuvette is typically cuboid in shape, with its lower surface and two lateral sides composed of frosted glass. The remaining two lateral sides are constituted by light-transmissive surfaces, crafted from fused optical glass through the melting and gluing of glass powder at elevated temperatures.

The quartz glass product exhibits a multitude of advantageous characteristics, including high transparency, high temperature resistance, corrosion resistance, high purity and favourable electrical insulation properties. However, it should be noted that quartz glass also has certain disadvantages, including brittleness, processing difficulty, susceptibility to scratches and sensitivity to ultraviolet light. 

Manufacturers of quartz products typically classify impurities based on the specific application environments. This classification of impurities can be broadly categorized into several types: visible impurities (such as bubbles, gas lines, color spots, and nodules), heavy metals, alkali metals, and hydroxyl groups.

At high temperatures, the quartz tube will undergo a chemical reaction with alkali metals, resulting in the formation of crystallization. These crystalline regions exhibit increased fragility, leading to the development of cracks. Potential sources of alkali metal contamination may include the following.
