SF-C0310USB-D3.9-PLUS-D9
SINCEREFIRST
The 3.9mm VGA Sensor Endoscope (Model: SF-C0310USB-D3.9-PLUS-D9) is a high-precision HD Inspection Camera designed for dual medical and industrial applications. Featuring a USB2.0 Interface, 90° wide field of view (FOV), and Borescope Camera with LED Light, this module delivers sharp, low-distortion imaging with TV distortion < -5.5%. Its 20–80mm focus range, F3.58 large aperture, and lightweight 3.00g design make it versatile for clinical diagnostics, industrial pipeline inspection, and security equipment maintenance. Engineered for reliability and ease of use, it supports YUV&MJPG output formats and UVC Protocol compatibility, ensuring seamless integration with mainstream devices.

The 3.9mm diameter probe (±0.10mm tolerance) penetrates tight gaps—from human body cavities to industrial pipelines—enabling non-destructive inspection without damaging surrounding structures.
The VGA Sensor combined with an F3.58 large aperture delivers high-contrast, detailed imaging. It excels at distinguishing subtle differences in tissue color (critical for medical use) and surface textures (ideal for industrial corrosion detection).
The USB2.0 Interface ensures rapid, stable data transfer, supporting real-time HD imaging without lag. Compatibility with UVC Protocol allows plug-and-play use with most computers and mobile devices, simplifying on-site operations.
The 90° Wide FOV provides comprehensive coverage, while TV distortion < -5.5% guarantees accurate image restoration—critical for clinical diagnosis (e.g., gastroenteroscopy) and industrial quality assessment (e.g., weld inspections).
The 20–80mm focus range adapts to both macro observations (e.g., cystoscopy) and long-distance inspections (e.g., pipeline corrosion), making it a dual-purpose solution for medical and industrial users.
Four integrated LED Lights illuminate dark or confined spaces, eliminating shadows that could obscure details. The lights are optimized for low heat emission, ensuring patient comfort in medical settings and device safety in industrial environments.
Designed to meet both medical endoscope standards and industrial non-destructive testing requirements, the module offers flexibility for healthcare facilities, oil/gas companies, and security firms.
Weighing only 3.00g, the module is easy to maneuver during procedures. Its robust design includes a steel sleeve and waterproof connector, resisting friction, chemical corrosion, and physical impact.

Ideal for gastroenteroscopy, cystoscopy, and other clinical procedures, the module supports PC-side image magnification and case archiving. Its low distortion and accurate color reproduction help clinicians identify abnormalities like polyps or inflammation.
Suitable for oil/gas pipeline inner wall corrosion detection and weld quality assessment, the module’s long-cable compatibility (10–30m optional) and waterproof design support remote push operations. The 90° FOV and 20–80mm focus range capture detailed images of pipeline defects.
Used to inspect lock internal mechanical structures and hidden monitoring camera wiring, the 3.9mm probe accesses narrow spaces, while the LED Lights illuminate dark corners. The module’s lightweight design and plug-and-play functionality simplify on-site maintenance.
Laparoscopic modules require anti-fogging design (lens heating or anti-fog coating), 3D imaging capability, instrument channel integration, and accurate color reproduction (to distinguish tissue oxygenation status).
Pipeline inspection modules typically use 10–30m cables with Kevlar tensile layers and waterproof connectors. These cables resist internal pipeline friction and chemical corrosion while enabling real-time image transmission during remote inspections.
3D endoscopes use dual-lens modules or splitter prisms to capture left/right eye images, which are synchronously output to a 3D display at ≥1080p/60fps. This ensures smooth, immersive visualization for complex minimally invasive surgeries.
TV distortion stems from lens optics and sensor alignment. This module minimizes distortion to < -5.5% via precision Active Alignment (AA) and optimized lens design, ensuring accurate image restoration for critical applications.
Yes. The LED Lights brightness is adjustable via the connected device’s software or the module’s control buttons, adapting to medical (low-glare tissue observation) and industrial (high-brightness pipeline inspection) environments.
