Quartz pendulous reed is the core component of flexible accelerometer. Its swing determines the range and resolution of accelerometer. The stability of swing and vibration frequency affects the bias value and scale factor repeatability of accelerometer. Different quartz glass materials and surface defects affect the performance of quartz pendulous reed to varying degrees, so the material selection and processing requirements of quartz pendulous reed are very strict.

The hemispherical resonator gyroscope is composed of hemispherical resonator, excitation cover and sensitive basement. All of them are made of fused quartz material with high quality factor and metallized on the surface. As the sensitive part of the gyro, the hemispherical resonator is the core of the hemispherical resonator gyro. Its machining surface accuracy, position accuracy and surface quality are the most key factors affecting the accuracy and performance of the hemispherical resonator gyro. The higher the machining accuracy of hemispherical resonator, the closer it is to the ideal resonator state, and the higher the gyro accuracy. The hemispherical resonator is made of fused quartz and is a hemispherical thin-walled shell with a central support rod, with a diameter of φ 15 ~ 60mm, wall thickness is generally 0.3-1.1mm, surface accuracy < 0.5um, inner and outer ball concentricity < 0.5um, surface roughness Ra < 0.025um, and quality factor Q value is higher than 107. The special-shaped spherical hemispherical resonator requires high surface accuracy and concentricity of inner and outer spheres, and the accuracy reaches sub micron level. Due to the hard and brittle quartz glass material, easy edge collapse, crack and embrittlement in processing, and special processing technology, the conventional processing method of spherical optical elements is not applicable, the qualified rate is very low, and the processing is very difficult.
After years of technical accumulation, we can successfully produce this part with high accuracy.

High precision CNC machining is used to complete the processing of drilling, inclined plane, groove area, cylindrical surface and thread, which realizes the effect of multi-channel experimental analysis.

Flow cells are essential components in analytical chemistry and biochemical research, enabling samples or reaction solutions to flow smoothly for detection and analysis. Usually made of optical glass or quartz, these materials are transparent and chemically stable, ensuring they don’t react with solutions and allowing light to pass through—perfect for optical detection systems. The typical design is cuboid-shaped, with both ends made for easy connection to pipelines, ensuring a seamless inflow and outflow of liquids. The pointed lower end facilitates draining and helps minimize residue buildup.
