Application of Dinghongrun Sapphire Metallization in Endoscope

Sapphire metallization Sapphire technology has important applications in endoscopic packaging, mainly because of its excellent optical properties, mechanical strength and biocompatibility, which makes it widely used in the field of medical devices, especially in endoscopic technology.

Background and advantages of sapphire metallization:

1. Advantages of sapphire materials ：
   • Optical transparency : Sapphire has extremely high optical transparency, especially in the ultraviolet to near-infrared spectral range, which can ensure that the transmission of optical signals in the endoscope is not affected.
   • Mechanical strength and corrosion resistance Sapphire is a very hard material, second only to diamond, so it has good scratch resistance and abrasion resistance. The endoscope needs to be in constant contact with human tissues. Sapphire can effectively prevent equipment damage.
   • Biocompatibility Sapphire is a biocompatible material, which can be safely used in medical devices to avoid rejection reaction of patients.
2. Purpose of metallization technology : Sapphire itself is an insulating material. In the endoscopic packaging, it is usually necessary to connect sapphire with other electronic components (such as electrodes, circuits, sensors, etc.). Metallization technology realizes electronic conductivity by depositing metal layers (such as titanium, aluminum, nickel, etc.) on the surface of sapphire, so that it can be effectively connected with other metal parts.

Specific applications of sapphire metallization in endoscopic packaging:

1. Connection of optical components : In the endoscope, optical lens, sensor, optical fiber and other components need to be packaged and connected through metallized sapphire materials. Metallization can realize the electrical connection between sapphire and other electronic components, ensure the stable transmission of optical signals, and maintain good mechanical fixation.
2. Sensor packaging : Various sensors (such as temperature sensor, pressure sensor, etc.) are often used in the endoscope. These sensors need to be embedded in the equipment and connected to the external circuit. The metallized sapphire provides a stable foundation for sensor packaging, which can effectively transmit signals and protect the sensor from external environment.
3. Packaging of protective housing : Sapphire material is often used as the protective shell of the endoscope. After metallization, it can be used as the structural material for electromagnetic shielding, heat dissipation and strength support to ensure the durability and stability of the endoscope in use.
4. High temperature resistance and corrosion resistance : The high-temperature stability and corrosion resistance of sapphire are very important in some medical environments requiring high-temperature disinfection. The metallized sapphire can maintain its performance in harsh environment without being affected by high temperature or chemical corrosion, thus extending the service life of the endoscope.

summary : The application of sapphire metallization technology in the endoscopic packaging makes the endoscope have higher optical performance, mechanical strength, durability and biocompatibility. Metallization can not only realize the connection between sapphire and other electronic components, but also enhance its corrosion resistance and resistance to temperature changes, thus meeting the high requirements for reliability and accuracy of medical equipment.
