OMNIVISION has announced the miniature 2-megapixel CMOS image sensor in square format for disposable and reusable endoscopes.

OMNIVISION, a developer of semiconductor solutions, including advanced digital imaging, analogue, and touch & display technology, announced the OH02B image sensor – the square 2-megapixel (MP) (1500x1500) resolution CMOS image sensor for gastrointestinal, ENT, orthopedic, surgical, dental, and veterinarian reusable and disposable endoscopes, catheters, and guide wires. It is available in the smallest form factor 2.5 x 2.5mm CameraCubeChip package (OCH2B) for disposable designs. It features OMNIVISION’s AntLinx proprietary technology, which provides the thinnest 4m interface connection directly from the endoscope camera to the camera control unit (CCU) tower. The OH02B imager and OCH2B camera will be demonstrated at COMPAMED Germany, 14th to 17th November, 2022, Hall 8a/P13.

“The medical industry is moving to single-use endoscopes to minimise 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.”

AntLinx long-reach digital interface

OMNIVISION’s AntLinx digital interface connects the OH02B/OCH2B from the endoscope camera to the CCU tower. It features only four thin micro-coaxial cables that reach 4m 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.

Latest image sensor technology in smallest form factor

The OH02B image sensor is built on OMNIVISION’s latest PureCel Plus-S stacked-die technology. It is available in the OCH2B CameraCubeChip package that features a small 2.5 x 2.5mm size with exceedingly high image quality for disposable endoscope designs.

Medical certifications streamline FDA approval process

OMNIVISION is ISO13485 certified and medical products are EMC and EMI tested, which helps to streamline the medical device OEM’s FDA approval process. The OCH2B is also biocompatible and waterproof, and the OH02B is autoclavable. It does not require tuning or calibration.

Samples of the OH02B imager and OCH2B camera are available now.
