OmniVision Announces Industry’s Highest Resolution Image Sensor for ENT, Cardiac, Arthro, OB-GYN and Uterorenal Endoscopes

SANTA CLARA, Calif.–(BUSINESS WIRE)–OmniVision Technologies, Inc., a leading developer of advanced solutions digital imaging solutions, today announced the OVMed® OH0FA image sensor and bridge chip OAH0428 for endoscopes and catheters. The OH0FA image sensor delivers 720×720 resolution at 30 frames per second (fps) – the highest resolution available for ENT, cardiac, arthro, OB-GYN, and utero-renal endoscopes, providing unparalleled visibility for surgeons to see and diagnose the disease at an early stage. The OAH0428 bridge chip, specially developed for 720×720 resolution compatibility, provides analog-to-digital conversion and flexibility for a variety of analog and digital inputs and outputs.

“OmniVision works with surgeons and medical device OEM for 15 years and our products have been used by surgeons in over 15 million procedures, so we understand surgeons’ needs and endoscope requirements,” said Ehsan Ayar, Medical Product Marketing Manager at OmniVision. “Based on this feedback, we designed the OH0FA image sensor to deliver the highest resolution at the best possible frame rate, with the flexibility to increase the frame rate to a lower resolution to meet procedures with different requirements. Additionally, we have incorporated a high level of flexibility with the OAH0428 bridge chip. »

The 720×720 resolution of the OH0FA represents a dramatic increase over the previous generation image sensor, the OVM6946, at 400×400. The OH0FA offers an optional range of resolution and frame rate combinations, depending on the procedural requirements: 720×720 at 30 fps, 600×600 at 40 fps, or 400×400 at 60 fps. The device’s high signal-to-noise ratio yields sharper, clearer images with excellent color fidelity, so surgeons can see the most realistic images to better diagnose and treat disease.

The OH0FA is a high performance 0.93 x 0.93 mm sensor in 1/18 inch optical format. Its 1.008µm pixel size is based on OmniVision’s PureCel®Plus-S pixel technology. This next-generation pixel technology also delivers high color fidelity and a 37.5dB signal-to-noise ratio for sharper images. In addition, PureCel®Plus-S enables the high full-well capacity of OH0FA, non-blooming and low power consumption. A version of OCHFA, based on OmniVision’s CameraCubeChip® technology, will soon be launched for single-use endoscopes.

Special features of the OAH0428 companion chip include HDR, auto start, pseudo-global shutter, improved NIR sensitivity and various security features. It is also autoclavable. The OAH0428 has a proprietary 4-pin analog interface that can transmit up to 4 meters. Exposure time and gain parameters can be sent from an external SPI control, automatically by the internal AEC/AGC OAH0428 or manually by the host.

OmniVision’s OVMed product line consists of reliable medical-grade components that have undergone extensive certification, qualification and testing. This increases the likelihood and speed of FDA certification for medical device OEMs, while providing hospitals, surgeons, and patients with a high level of confidence in the endoscope.

The OH0FA image sensor and OAH0428 bridge chip are now available for sampling in OmniVision’s hCSP chip-scale package with 100-micron thick cover glass and anti-reflective coating. OmniVision offers an evaluation kit with a pre-tested OVMed image signal processor to enable rapid evaluation and development.
