OMNIVISION Unveils Mini 2 Megapixel CMOS Image Sensor for Endoscopes

OMNIVISION has debuted the OH02B image sensor—the first square 2 megapixel (MP) (1500 x 1500) resolution CMOS image sensor for gastrointestinal, ENT, orthopedic, surgical, dental, and veterinarian reusable and disposable endoscopes, catheters, and guide wires.

The sensor is available in the smallest form factor 2.5 x 2.5 mm CameraCubeChip package (OCH2B) for disposable designs. It features OMNIVISION’s AntLinx proprietary technology, which provides the thinnest 4-meter interface connection directly from the endoscope camera to the camera control unit (CCU) tower. 
 
“The medical industry is moving to single-use endoscopes to minimize cross-contamination and improve patient safety. CCD-based image sensors cannot meet today’s high-performance endoscope requirements and are being phased out,” said Richard Yang, senior marketing manager, OMNIVISION. “CMOS image sensors, such as the OH02B, are critical for the disposable endoscope market because they enable high resolution and small size, generate very low heat at the tip of the scope design, and are cost-effective for one-time use. OMNIVISION’s CameraCubeChip design provides further size advantages and simplifies design resources and the supply chain.”
 
OMNIVISION’s AntLinx digital interface connects the OH02B/OCH2B from the endoscope camera to the CCU tower. It features four thin micro-coaxial cables that are 4 meters long. It is not affected by noise or electromagnetic interference and has minimal electromagnetic conduction. AntLinx delivers superior video quality and reduces interface conversion requirements, even for long-reach applications like gastrointestinal endoscopy.
 
The OH02B image sensor is built on OMNIVISION’s latest PureCelPlus S stacked-die technology. It is available in the OCH2B CameraCubeChip package that features a small 2.5 x 2.5 mm size with exceedingly high image quality for disposable endoscope designs. The OCH2B is also biocompatible and waterproof, and the OH02B is autoclavable. It does not require tuning or calibration.
