Quartz tubes are characterized by a low coefficient of thermal expansion. This means that the dimensional change of quartz tubes is relatively small when the temperature changes. Specifically:

1. Advantages

- High stability: low coefficient of thermal expansion enables quartz tubes to maintain a more stable size and shape in different temperature environments, reducing deformation, rupture and other problems caused by thermal expansion and contraction.

- Adaptable to high-temperature environments: can be used in high-temperature conditions without being damaged by severe thermal expansion. For example, in some high-temperature industrial furnaces, quartz tubes can withstand temperatures of thousands of degrees while maintaining structural integrity.

- Guarantee of accuracy: For applications requiring high dimensional accuracy, the low thermal expansion of quartz tubes ensures that the accuracy and performance of the equipment will not be affected by temperature changes.

2. Influencing Factors

- Chemical composition: The purity and impurity content of a quartz tube affects its coefficient of thermal expansion. Higher purity quartz tubes typically have lower coefficients of thermal expansion.

- Temperature range: Although the coefficient of thermal expansion of quartz tubes is low, it can still vary under extreme high or low temperature conditions. Different temperature ranges affect the coefficient of thermal expansion to different degrees.

- Structure and Size: Structural parameters such as wall thickness and diameter of the quartz tube also have an effect on the thermal expansion characteristics. In general, quartz tubes with larger wall thicknesses have relatively less thermal expansion.

Advantages of quartz tubes in light source applications

1. Good light transmission

- High transparency: quartz tube for visible light and ultraviolet, infrared and other different wavelengths of light have a high transmittance rate, can make the light source issued by the light through the full, reduce the loss of light.

- Good uniformity:can ensure the uniformity of light through the quartz tube, to avoid uneven light spots and other problems, to improve the lighting effect of the light source.

2. High temperature performance

- Adapt to high-intensity light source: for some high-intensity light sources, such as xenon lamps, mercury lamps, etc., will produce a lot of heat. Quartz tube can withstand these high temperatures without deformation or damage, to ensure the normal operation of the light source.

- Strong stability: under long time high temperature working conditions, the performance of the quartz tube will not change significantly, ensuring the stability and reliability of the light source.

3. Chemical stability

- Anti-corrosion: quartz tube has strong chemical stability, is not easy to be acid, alkali and other chemicals corrosion. In some special light source application environment, such as occasions containing corrosive gases or liquids, quartz tube can ensure the service life of the light source.

- No pollution: no chemical reaction with the light source, will not release harmful substances, to ensure the purity of the light source.

4. High mechanical strength

- Good seismicity: able to withstand certain mechanical shock and vibration, not easy to rupture. During transportation and use, it can protect the light source from damage.

- Easy to process: can be cut, bent and other processing according to the needs of different light sources to meet a variety of complex light source design requirements.

Quartz tube in the light source application of specific areas
