This 3.9mm USB Borescope Inspection Camera Module With Light is equipped with a VGA high-definition sensor (resolution: 640×480) and features an ultra-slim 3.9mm diameter design that breaks through the observation limitations of narrow spaces. The module is fitted with a 90° wide field of view (FOV), combined with an ultra-short focal length of 1.074mm and an F3.58 aperture, enabling a wide focusing range of 20mm-80mm. It can clearly capture observation targets at different distances without frequent adjustments. Its TV distortion rate is strictly controlled within 5.5%, which can truly restore the spatial proportion and detailed features of the target. The interface adopts the USB2.0 UVC standard, is equipped with a Mini USB-5P connector, supports dual-format output of YUV and MJPG, and enables plug-and-play functionality without complex drivers. Additionally, it has a built-in manually switchable LED fill light, which can provide stable light sources in low-light and confined environments, fully adapting to the visualization needs of multiple fields such as medical treatment, pet diagnosis and treatment, and industrial testing.

Product Advantage ◢

  1. Miniature Design: With an extremely slim diameter of 3.9mm, it can easily penetrate hard-to-reach areas such as human body cavities and precision gaps of equipment. Moreover, it reduces patient discomfort during medical testing and avoids the need for disassembling complex equipment in industrial scenarios, thereby improving testing efficiency.

  2. Convenient Compatibility: The USB2.0 UVC interface supports plug-and-play, being compatible with mainstream systems like Windows and Mac as well as various testing software. The Mini USB-5P connector is adaptable to multiple device ports.

  3. Integrated Optical Design: It integrates three functions—light collection, imaging, and illumination—into the 3.9mm diameter tube body. No external light source is required to obtain uniform illumination in confined spaces, eliminating shadow interference and shortening the system integration cycle.

  4. Wide-Range Focusing System: The 20-80mm continuous focusing range covers both close-range details and long-distance outlines. Cooperated with the fixed F3.58 aperture, it reduces repeated focusing operations during pipeline depth detection and improves the efficiency of streamlined operations.

  5. Geometric Distortion Suppression: Under the 90° wide-angle field of view, the TV distortion rate is strictly controlled within 5.5%, ensuring high straight-line retention at image edges. This facilitates defect measurement and size calibration, meeting the quantitative analysis needs of precision testing.

Application of Endoscope Camera Module

  • Industrial Manufacturing & Maintenance: Used in integration into internal inspection instruments for small motors, spindle condition monitors for CNC machine tools, and endoscopic detectors for welds in petrochemical pipelines to conduct non-destructive visual inspections of equipment interiors.

  • Automotive Maintenance: Can be integrated into carbon deposit detectors for automobile engines and internal wear inspection mirrors for gearboxes, allowing observation of internal conditions without disassembly.

  • Special Equipment Safety Inspection: Suitable for devices such as gap inspection mirrors for elevator traction machines and pollution observation instruments for central air-conditioning ducts, assisting in daily safety inspections and fault diagnosis.

  • Security & Public Safety: Can be embedded in devices like security and explosive ordnance disposal mirrors and internal wall inspection instruments to inspect concealed spaces and ensure public safety.
