OmniVision Technologies Inc. demonstrated its OVMed OH0FA image sensor and OAH0428 bridge chip for endoscopes and catheters during MD&M Minneapolis. The OH0FA image sensor offers 720x720 resolution at 30 frames per second (fps), which the company states is the highest available resolution for ENT, cardiac, arthro, OB-GYN, and utero-renal endoscopes. The OAH0428 bridge chip, compatible with 720x720 resolution, offers analog-to-digital conversion and flexibility for a variety of analog and digital inputs and outputs. 

“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,” stated Ehsan Ayar, medical product marketing manager at OmniVision, in a news release. “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.”

Built on OmniVision’s PureCelPlus-S pixel technology, the OH0FA is a 1.008-µm-pixel high-performance 0.93x0.93 mm sensor in a 1/18 in. optical format. This next-generation pixel technology also provides the high color fidelity and signal-to-noise ratio of 37.5 dB for crisper images. A version of the OCHFA, based on OmniVision’s CameraCubeChip technology, will be launched soon for single use endoscopes.

Special features of the autoclavable OAH0428 companion chip include HDR, auto-start, pseudo-global shutter, enhanced NIR sensitivity, and various security functions, the company reported. 

OmniVision’s OVMed product line consists of medical-grade components that undergo comprehensive certification, qualification, and testing, the company reported. 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 will also be at CompaMed, Nov. 15-18, Hall 14 / F40, and MD&M East, Dec. 7-9, Booth 828.
