Laboratory and Chemical ApplicationsQuartz light guide rods utilize the principle of total internal reflection for transmitting light signals. When light travels from an optically dense medium to an optically less dense medium, if the angle of incidence is greater than or equal to the critical angle, the light will be totally reflected back into the original medium, thereby achieving light transmission. Within a quartz light guide rod, light undergoes continuous total internal reflection at the inner walls of the rod, thereby traveling along the length of the rod towards the target location.

There are two primary methods for producing quartz rods: the continuous method and the flame fusion method (also known as the gas fusion method).
Continuous Method: In this method, quartz sand is fed from the top into a furnace, which comprises a metallic quartz crucible surrounded by electric heating elements. The quartz sand melts at high temperatures. The molten material then passes through a shaping orifice at the bottom of the crucible, producing rods, tubes, sheets, or other various specified product forms.
Flame Fusion Method: This method involves using hydrogen and oxygen to melt colorless quartz crystal. The molten material is formed into quartz glass through the melting and congealing of crystalline particles in the flame. The quartz glass is then removed from the flame through different methods and processed into quartz rods of the desired shape.
High-Temperature Resistance
Quartz glass exhibits excellent high-temperature resistance, maintaining stability in high-temperature environments.
Low Thermal Expansion Coefficient
The thermal expansion coefficient of quartz glass is extremely low, ranging from 1/12 to 1/20 of that of ordinary glass, contributing to its stability under temperature variations.
Corrosion Resistance
Quartz glass is resistant to a variety of acids, bases, and salts, with the exception of hydrofluoric acid and hot phosphoric acid above 300 degrees Celsius.
High Light Transmission Rate
The light transmission rate can reach 99.9%, ensuring high transmittance of light signals during transmission.
Application Scenario
Communication Field
In optical fiber communication systems, quartz light guide rods serve as a medium for transmitting light signals from the transmitter to the receiver, enabling high-speed and high-capacity data transmission.
They are also used in equipment such as lasers and optical amplifiers to enhance the performance and stability of communication systems.

Quartz light guide rods exhibit excellent long-term stability in various environments. They possess a high degree of chemical stability, allowing them to maintain their performance and integrity in a wide range of chemical environments. Additionally, the thermal expansion coefficient of quartz glass is among the lowest of common industrial glasses, which means that it maintains good dimensional stability during temperature changes and is highly resistant to thermal shock.
Quartz light guide rods possess extremely high chemical stability and are nearly unreactive with most acidic and alkaline substances, except for hydrofluoric acid. This corrosion resistance makes them invaluable in environments where frequent contact with corrosive materials is common.
Quartz stirring rods offer superior high-temperature resistance and chemical stability compared to plastic stirring rods. Additionally, they possess high structural strength, are less prone to breakage, and have a long service life.

Frequently asked questions
Quartz glass is a hard and brittle material with excellent physical and chemical properties, extremely high mechanical hardness, good electrical insulation, high temperature and corrosion resistance, low and stable delay performance, good light transmittance, etc. It is widely used in semiconductors, optics, electricity, chemistry, aerospace, automobiles and other fields. Hard and brittle materials are difficult to process, and many fields urgently need cutting processes with small edge collapse, less material loss, low cross-section roughness, and a wide cutting thickness range. The traditional cutting method of quartz glass is mechanical cutting, that is, wheel cutting. Non-traditional cutting methods include water jet cutting, electrochemical discharge wire cutting, continuous laser cutting, etc. Mechanical cutting has low cost, but the contact between the wheel and the material causes large tool wear, and the material is easily contaminated by the tool. Quartz glass is prone to edge collapse, microcracks, and residual stress, which affects the strength and performance of the material! It is difficult to achieve curve cutting and requires post-processing, such as grinding and polishing. Laser cutting does not directly contact the material, has no contact stress, and can perform complex curve cutting. Picosecond laser has the advantages of small spot diameter, high precision, short action time with the material, and small action area, and is suitable for the processing of hard and brittle materials.
