Mini 3.9 mm Endoscope Camera Module With Light
This Mini 3.9mm Endoscope Camera Module with Light from SincereFirst is a professional medical-grade core component independently developed and produced by Guangzhou Sincere Information Technology Ltd. In terms of core parameters, the module adopts a Separated structural design, with a diameter of only 3.9mm (±0.10mm). It is equipped with a 1/10-inch VGA sensor and 4 high-brightness LED fill lights, providing sufficient light sources and a solid foundation for clear imaging even in low-light environments. Built with a high-performance image processor and digital signal processor, it controls TV distortion to less than -5.5% through advanced image optimization algorithms, ensuring the output of professional-grade high-definition images that meet medical diagnosis standards. In terms of optical performance, the module's focal length is precisely controlled at 1.074mm, with a field of view (FOV (D)) of 90°, a focusing range covering 20mm-80mm, and an F.NO of 3.58mm. It can accurately capture fine details of the target area, fully meeting the strict requirements for image precision in medical inspections.


The most core advantage of this module lies in its full support for the OTG protocol, which brings extremely high convenience and flexibility to users in practical applications: Relying on the USB2.0 interface and UVC protocol compatibility, the module can directly achieve "Plug & Play" with devices running mainstream operating systems such as Android, Windows, and Linux without the need for additional driver installation. There is no need for back-and-forth data transmission. In addition, the module supports dual output formats (YUV and MJPEG), which can be flexibly switched according to the image processing capabilities of different devices, further expanding the scope of adaptation.
In terms of production processes and compliance, the module is manufactured using SMT and AA (Active Alignment) processes: The SMT process ensures the soldering precision of components and the overall structural stability of the module, reducing the risk of failures during long-term use; the AA process accurately calibrates the position of optical components to ensure the consistency of optical performance across all modules, avoiding the impact of batch differences on usage. At the same time, the module has passed multiple international tests and certifications, including CE, FCC, RoHS, and Reach, complying with safety, environmental protection, and electromagnetic compatibility standards in major global markets. It can be safely used in medical, industrial, and other scenarios at home and abroad. The module lens is equipped with a Steel Shell and features an IP67 waterproof rating, facilitating cleaning and disinfection in medical scenarios. It also supports multiple USB cable length options (1m, 2m, 3m) to adapt to the installation and usage needs of different scenarios.
Features
- Ultra-miniature Size: 3.9mm (±0.10mm) diameter integrates easily into laparoscopes/small-caliber oral endoscopes, minimizing patient trauma. The 1/10-inch VGA sensor and medical-grade materials meet safety/precision needs for cavity inspection and minimally invasive surgery.
- High-Quality Imaging: Equipped with image/digital signal processors and advanced algorithms, it reduces TV distortion to < -5.5%. 4 LED fill lights, 1.074mm focal length, 90° FOV, and 20-80mm focusing range ensure clear details in dark/narrow spaces.
- OTG + UVC Compatibility: Supports OTG/UVC protocols, compatible with Android/Windows/Linux/MAC OS devices without drivers. Plug-and-play reduces deployment costs and operational complexity for medical mobile terminals or industrial fixed devices.

- IP67 Waterproof + Multi-spec Cables: IP67 waterproofing adapts to medical disinfection and industrial humid environments for easy maintenance. 1m/2m/3m USB cables fit different wiring/detection distance needs.
- Safety & Reliability: Uses SMT for better anti-interference and stability, and AA for consistent optical precision. Certified by CE, FCC, RoHS, Reach, it meets global medical/industrial standards, lowering procurement risks.
- Dual Output Formats: Supports YUV and MJPEG , adapting to more devices via flexible switching.
