Material Properties

1. Optical performance

High transmittance: With a transmittance of over 90% in the ultraviolet (190nm) to near-infrared (2500nm) wavelength range, it is suitable for broadband light guidance requirements.

Low dispersion: The dispersion coefficient is extremely low, which can reduce color difference in optical signal transmission and improve imaging quality.

2. Thermal stability

The coefficient of thermal expansion is only 0.5 × 10 ⁻⁶/℃ (20-1000 ℃), and the size is stable at high temperatures, making it suitable for environments with drastic temperature changes.

Resistant to high temperatures up to 1713 ℃, suitable for high-temperature optical systems.

3. Mechanical and Chemical Properties

Mohs hardness is about 7, with strong wear resistance; High chemical stability, resistant to acid and alkali (except hydrofluoric acid) corrosion.

manufacturing process

Raw materials and melting: High purity quartz (SiO ₂>99.99%) is melted in an electric furnace above 1760 ℃ and rapidly cooled to form an amorphous structure.

Processing difficulty: It is necessary to solve the problem of removing bubbles during high-temperature melting and control the impurity content (<0.01%) to ensure purity.

Application field

1. Optical communication and photonic devices: Low loss waveguides (propagation loss<0.1db/cm) can be manufactured using femtosecond laser direct writing technology for optical communication modules.

2. Optical system: used as a lens and window material for precision instruments such as microscopes and telescopes.

3. Industry and Research: High temperature observation windows, semiconductor processing equipment components, and corrosion-resistant light guiding components.

With its comprehensive performance, fused silica light guide block is irreplaceable in high-end optical and industrial fields.

Precautions

Cleaning and maintenance: Use a soft cleaning cloth and specialized cleaning agent to clean and avoid scratching the surface.

Storage environment: Store in a dry, well ventilated environment to prevent moisture and mold.

Usage: During use, avoid severe vibration and collision to avoid affecting its optical performance.
