SINCEREFIRST
The 3.9mm USB Medical Endoscope Camera Module is a high-performance imaging solution engineered by SincereFull for both medical minimally invasive procedures and industrial precision detection. Integrating a VGA sensor and a MINI USB2.0 interface, this module features an ultra-short focal length of 1.074mm and an F3.58 aperture, delivering accurate imaging across an ultra-wide focusing range of 20mm–80mm. With a 90° diagonal field of view (FOV) and strict TV distortion control of < -5.5%, it ensures clear, low-deformation images to support precise diagnosis and inspection. Equipped with built-in LED lights, it eliminates dark corners and provides uniform lighting in confined spaces, while the plug-and-play USB2.0 functionality enables fast integration with surgical monitoring equipment and industrial detection hosts. Its 3.9mm ultra-fine diameter balances high resolution and flexible operation, making it a reliable tool for medical visualization and mechanical fault detection.

The combination of VGA sensor and 90° wide-angle FOV covers a larger detection area, ensuring no critical details are missed during medical examinations or industrial inspections.
TV distortion of < -5.5% guarantees minimal image edge deformation, which is crucial for accurate measurement and diagnosis in both clinical and industrial scenarios.
The 20mm–80mm focusing range and F3.58 large aperture adapt to different depth lesions in the human body and hidden mechanical structures, eliminating the need for frequent module replacement.
The ultra-fine 3.9mm diameter supports seamless integration with minimally invasive surgical instruments, reducing patient discomfort in medical procedures and enabling access to narrow mechanical parts.
Four built-in LED lights provide uniform supplementary lighting, effectively eliminating dark corner effects in cavity or small-space inspections.
The LED lighting system improves imaging quality in low-light environments, ensuring clear visualization of carbon deposits, cracks, or tiny lesions that are easily overlooked.

Minimally invasive surgery: Supports abdominal, ENT, and urinary system endoscopic integration, enabling high-definition observation of lesions through 3.9mm instrument channels.
Endoscopic diagnosis: Facilitates screening of internal lesions in the digestive tract and respiratory tract, providing clear imaging for early disease detection.
Engine inspection: Penetrates hidden parts such as cylinders and crankcases to check for carbon deposits, cracks, or foreign bodies, supporting vehicle maintenance and fault troubleshooting.
Mechanical structure detection: Accesses narrow gaps of precision equipment to identify potential defects, reducing equipment failure risks.
Medical modules prioritize biocompatibility, sterilization performance, and high image quality, and must comply with FDA/CE certifications. Industrial modules focus on durability, such as corrosion resistance, and wide-temperature operation ranging from -20°C to 70°C, along with special light source configurations.
Ear and nasal spaces are narrow. Modules with a diameter of less than 3mm can reduce patient discomfort, while maintaining high resolution of ≥300 line pairs/mm to identify tiny lesions that are easily missed.
Choose modules with oil-proof lenses, adjustable focal lengths (e.g., 10–100mm), and strong LED lights. Some modules with magnetic probes or 360° rotating heads are preferred, as they can inspect engine dead angles more comprehensively.
