As an important non-destructive testing tool, industrial endoscopes have shown a rapid development trend worldwide in recent years. The technological progress and localization process of industrial endoscopes are of great significance for improving the level of industrial testing in our country.

The development trend of industrial endoscopes

The development of industrial endoscope technology is moving towards intelligence, high definition and functional integration, and its application fields are also constantly expanding.

Technological iteration and upgrading: Modern industrial endoscopes are actively integrating cutting-edge technologies such as 4K ultra-high-definition imaging, artificial intelligence (AI), 5G, and the Internet of Things. 4K ultra-high-definition imaging technology enriches image details and helps detect even tinier defects. AI technology, especially the AI defect recognition function, can automatically analyze images and assist inspectors in quickly determining the status of equipment, thereby enhancing the automation level and accuracy of inspection. The application of 5G technology has enabled remote real-time collaboration, allowing experts to participate in diagnosis without having to be present at dangerous or remote sites. In addition, the integration of three-dimensional measurement functions enables industrial endoscopes not only to "see" but also to precisely quantify the discovered defects.

Product form and function expansion: At the product level, flexible endoscopes currently hold a dominant position in the market, with a share of approximately 60%, due to their ability to adapt to complex pipeline and equipment structures. Meanwhile, the market has a continuous pursuit of smaller diameter probes, and ultra-fine endoscopes with a diameter of less than 3mm have become a research and development hotspot. Industrial endoscopes are also evolving from simple detection tools to multi-functional devices that integrate diagnostic, therapeutic and sampling functions. Future products may also integrate multiple sensors such as temperature, pressure and even chemical analysis sensors, providing more comprehensive equipment status information.

The application scenarios continue to expand: The traditional application fields of industrial endoscopes include the automotive, aerospace, petrochemical and other industries. With the advancement of technology and the development of industries, its application in new fields such as new energy (such as battery pack testing), semiconductors (such as packaging testing), railways, and construction is constantly deepening. For instance, the dedicated endoscopes for battery pack inspection developed by local enterprises such as Shenzhen Guantai for the new energy sector have received a favorable market response.

The strategic significance of the localization of industrial endoscopes

The localization of industrial endoscopes holds profound significance for breaking foreign technological monopolies, reducing user costs, empowering domestic industrial chains, and ensuring the security of supply chains in specific fields.

Breaking monopolies and achieving technological autonomy: For a long time, the global industrial endoscope market, especially the high-end market, has been dominated by international giants such as Olympus and Karl Storz. Through continuous technological research and development, Chinese enterprises represented by Shenzhen Yatai Optoelectronics, Guantai and Jietai have made breakthroughs in core components such as CMOS image sensors, bypassing the monopoly of Japanese enterprises in CCD sensors. Take medical endoscopes as an example. The market share of soft endoscopes of domestic brand Kaili Medical has risen from nearly zero to over 10%. In terms of manufacturing processes, domestic enterprises have also made remarkable progress. For instance, O-film has enhanced the sealing performance and circuit stability of camera modules through the "integrated potting process" and "high-precision wire bonding technology".

Reducing costs and enhancing accessibility: One of the most direct advantages of domestic industrial endoscopes is their price. For products of the same performance, the prices of domestic brands are usually only one half to one third of those of imported brands. This has significantly reduced the procurement and maintenance costs of testing equipment for enterprises in downstream industries such as aviation, aerospace, automobiles, and petrochemicals, enabling more small and medium-sized enterprises to adopt advanced testing tools and enhancing the overall equipment safety level and quality control capabilities of the industry.

Promoting the development of the industrial chain and service optimization: Localization has driven the growth of the domestic endoscope industrial chain, giving rise to a number of innovative enterprises with distinctive features, such as Shenzhen Weishi Optoelectronic Technology (developing intelligent 3D defect detection endoscopes). At the service level, local manufacturers can offer more prompt after-sales response, flexible customized services, and non-standard probe customization tailored to specific needs. For instance, Li Peng, the vice president of Beijing Friendship Hospital, pointed out that for the product improvement demands raised by clinical doctors, domestic manufacturers can usually complete the modifications and send samples within a week. This response speed is hard for imported manufacturers to match.

Ensuring supply chain security and enhancing international competitiveness: In key areas related to national security such as aerospace, energy and power, and military industry, promoting the localization of industrial endoscopes helps ensure the independent control of the core inspection tool supply chain and reduce the risk of being "strangled" caused by fluctuations in the international economic and trade environment. With the maturation of domestic products in terms of technology and quality, some Chinese enterprises have also begun to enter the international market by adopting the strategy of "high cost performance + customized services", expanding their business in regions such as Southeast Asia and India, and enhancing the competitiveness of Chinese brands in the global market.

In conclusion, industrial endoscopes are developing rapidly in the direction of technological intelligence, functional integration and diversified applications. In this process, localization has played a crucial role: it not only broke the long-term monopoly of foreign manufacturers, significantly reducing user costs, but also promoted market popularization through services that are closer to local demands, and laid the foundation for ensuring supply chain security in key areas and developing independent core technologies.

In the future, with the continuous upgrading of China's manufacturing industry and the increasing demand for non-destructive testing, the localization process of industrial endoscopes will be further deepened. It is expected that by 2030, the market size of industrial endoscopes in China will exceed 4 billion yuan. This means that domestic industrial endoscope technology will play a more significant role in enhancing China's industrial inspection level and ensuring the safe operation of industrial equipment.
