As a key tool in dental diagnosis and treatment, dental endoscopes need to achieve high-definition imaging in the narrow spaces of the oral cavity (such as the posterior dental region and gingival sulcus), while meeting the requirements of frequent disinfection, flexible operation, and medical compliance. The endoscope camera module equipped with OmniVision Technologies' OCHFA10 CMOS sensor can accurately match the application scenarios of dental endoscopes with its targeted parameter design and performance advantages, providing technical support for dental diagnosis and treatment.
The internal space of the oral cavity is narrow and structurally complex. Conventional lenses are often restricted by space and difficult to reach key diagnosis and treatment areas. Meanwhile, frequent disinfection is required after treatment to avoid cross-infection, which puts dual demands on the size and material of the lens. The core advantage of this camera module lies in its 1.6mm-diameter plastic lens design with a steel shell: the ultra-small diameter of 1.6mm can flexibly extend into narrow parts of the oral cavity, such as the posterior dental region and around wisdom teeth, without excessive stretching of oral tissues, reducing patient discomfort. The steel shell on the outer layer of the lens enhances structural strength, resisting possible collisions or friction during diagnosis and treatment, and extending the service life.
At the same time, the plastic lens has excellent chemical stability and is compatible with common dental disinfection methods such as ethylene oxide (ETO) sterilization and alcohol wiping. No material aging or optical performance degradation occurs after disinfection, fully meeting the core needs of "high-frequency disinfection + long-term durability" in the oral medical scenario.
High-Definition Imaging Capability: The equipped OCHFA10 sensor supports 0.5MP pixels (700x700 resolution) with a pixel size of 1.008μm×1.008μm. Compared with traditional VGA-level (640x480) dental endoscopes, it can more clearly present the surface texture of teeth and details of gingival margins, and even capture 0.1mm-level early caries traces. The maximum frame rate of 30FPS ensures smooth real-time images without lag, allowing dentists to dynamically observe the patient's occlusion status or gingival dynamic responses.
Precise Illumination Configuration: The lens integrates 4 01005-sized LED beads. These beads are small in size and provide concentrated illumination, which can targetedly illuminate the diagnosis and treatment area, avoiding shadows in the oral cavity (such as between adjacent teeth and in the gingival sulcus) that affect observation. Combined with an F5.0 aperture and 0.418mm focal length, it can maintain uniform image brightness during close-range imaging, neither stimulating the patient's eyes with strong light nor causing missed diagnosis of lesions due to insufficient light.
Operational Flexibility: It adopts a separated design + manual focus function. The separated structure allows flexible adjustment of the placement of the lens and the host, so that dentists feel no cable drag when holding the lens. Manual focus can accurately lock the lesion area (such as the opening of a carious tooth and the depth measurement point of the gingival pocket), without relying on the "waiting response time" of auto-focus, improving diagnosis and treatment efficiency.
System Compatibility: It outputs data at USB2.0 speed via a Micro USB interface and supports the UVC protocol, which can be directly connected to mainstream devices such as the display screen of the dental unit and laptops without additional driver adaptation. It supports YUY/MJEPG output formats, which can not only meet the real-time image transmission needs of diagnosis and treatment but also store images for medical record filing or subsequent diagnosis and treatment comparison, conforming to the dental workflow of "real-time diagnosis + medical record management".
Oral medical equipment needs to pass strict international certifications to ensure safety in use. This module fully meets medical-grade requirements in terms of production and compliance: it is manufactured using SMT (Surface Mount Technology) and AA (Active Alignment) processes, which can ensure the precise alignment of the optical center of the lens with the center of the sensor, avoiding imaging deviation caused by assembly errors. At the same time, it has passed international certifications and tests including CE, FCC, RoHS, and REACH, and complies with medical device specifications in terms of electromagnetic compatibility (avoiding interference with other dental equipment such as dental drills) and restriction of hazardous substances (protecting the health of patients and dentists), providing reliable quality assurance for oral diagnosis and treatment.
