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

OmniVision Announces Industry’s Highest-Resolution Image Sensor for ENT, Cardiac, Arthro, OB-GYN and Utero-Renal Endoscopes (Graphic: Business Wire)
“OmniVision has been working with surgeons and medical device OEMs for the past 15 years, and our products have been used by surgeons in well 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 have designed the OH0FA image sensor to offer the highest resolution at the best frame rate possible, with the flexibility to increase the frame rate at a lower resolution to cater to procedures with different requirements. Additionally, we have built in a high level of flexibility with the OAH0428 bridge chip.”
The OH0FA’s resolution of 720×720 represents a dramatic increase when compared with the previous generation image sensor, the OVM6946, at 400×400. The OH0FA offers an optional range of resolution and frame rate combinations, based on the procedure requirements: 720×720 at 30 fps, 600×600 at 40 fps or 400×400 at 60 fps. The high signal-to-noise ratio of the device results in sharper, crisper 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 0.93×0.93 mm sensor in a 1/18 inch optical format. Its 1.008 µm pixel size is built on OmniVision’s PureCel®Plus-S pixel technology. This next-generation pixel technology also provides the high color fidelity and signal-to-noise ratio of 37.5 dB for crisper images. Additionally, PureCel®Plus-S enables the OH0FA’s high full-well capacity, zero blooming and lower power consumption. A version of the OCHFA, based on OmniVision’s CameraCubeChip® technology, will be launched soon for single use endoscopes.
Special features of the OAH0428 companion chip include HDR, auto-start, pseudo-global shutter, enhanced NIR sensitivity, and various security functions. It is also autoclavable. The OAH0428 has a proprietary 4-pin analog interface that can transmit up to 4 meters. Exposure time and gain settings can be sent from an external SPI control, automatically by the OAH0428 internal AEC/AGC or manually by the host.
OmniVision’s OVMed product line consists of medical-grade, trusted components that undergo comprehensive 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 device.
The OH0FA image sensor and OAH0428 bridge chip are available for sampling now in OmniVision’s hCSP chip scale package with 100 micron thick cover glass and an anti-reflective coating. OmniVision offers an evaluation kit with a pretested OVMed image signal processor to enable rapid evaluation and development.
