Spray Coating Process for LiDAR Extinction Tubes - Tsingcarbo

As the core component of LiDAR (Light Detection and Ranging) systems, the extinction tube plays a crucial role in suppressing stray light, reducing signal interference, and improving detection accuracy. To address the technical pain points of high reflectivity and unstable performance of traditional LiDAR extinction tubes, Tsingcarbo has independently developed a high-performance spray coating process specifically for LiDAR extinction tubes, breaking through key technical bottlenecks and providing a reliable solution for the upgrading of LiDAR optical components.

Core Technology: Customized Spray Coating Process for LiDAR Extinction Tubes

Leveraging our profound expertise in nanomaterial research and optical coating technology, we have tailored a spray coating process exclusively for LiDAR extinction tubes. This process integrates advanced ultrasonic atomization technology and nanomaterial dispersion technology, ensuring that the coating is uniformly deposited on the inner and outer surfaces of the extinction tube with high precision.

The spray coating process adopts high-stability nanocarbon-based coating materials, which have excellent adhesion and mechanical durability. After coating, the extinction tube can maintain stable performance in harsh working environments such as high temperature, high humidity and frequent vibration, meeting the long-term service requirements of automotive, industrial and aerospace LiDAR systems.

Outstanding Performance: Total Hemispherical Reflectivity Below 1.5%

The core advantage of our spray coating process lies in its excellent light extinction performance. After professional testing, the total hemispherical reflectivity of the LiDAR extinction tube treated by our process is stably controlled below 1.5%, which is far lower than the industry average level. This ultra-low reflectivity performance can effectively absorb stray light inside the LiDAR system, block the secondary reflection path of light, significantly reduce signal noise and false detection rate, and further improve the detection accuracy and distance measurement stability of the LiDAR system.

In addition, the coated extinction tube also has excellent optical consistency, and the reflectivity error of each part of the tube body is less than 0.3%, ensuring the uniform light extinction effect of the entire optical path, which is essential for the stable operation of high-precision LiDAR systems such as autonomous driving and intelligent robots.

Effect Comparison: Before and After Coating

The following figure shows the obvious effect comparison between the LiDAR extinction tube before and after the spray coating treatment. It can be clearly observed that the surface of the extinction tube without coating has obvious light reflection, which is easy to produce stray light interference; after the spray coating treatment, the surface presents a uniform matte black effect, with strong light absorption capacity and almost no obvious reflection, which fully reflects the excellent extinction performance of our coating process.

Application Value: Empowering the Upgrade of LiDAR Industry

With the rapid development of autonomous driving, intelligent transportation, industrial detection and other fields, the demand for high-performance LiDAR systems is growing day by day, and the performance requirements for core components such as extinction tubes are also increasing stricter. Our spray coating process for LiDAR extinction tubes not only solves the technical problems of traditional products, but also has the advantages of high production efficiency and strong scalability, which can meet the mass production needs of different specifications and models of extinction tubes.

This technology not only helps LiDAR manufacturers improve product performance and core competitiveness, but also promotes the technological progress of the entire LiDAR industry, and provides strong technical support for the popularization and application of intelligent equipment such as autonomous vehicles and industrial robots.
