OMNIVISION’s OVMed® OH0FA is a high performance 0.93 x 0.93 mm analog image sensor in a 1/18 inch optical format. The sensor provides 720 x 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 diseases.
Built on OMNIVISION’s PureCel®Plus-S pixel technology, the OH0FA, with its 1.008 µm pixel size provides the high color fidelity and signal-to-noise ratio of 37.5 dB for crisper and more realistic medical images. Additionally, PureCel®Plus-S offers high full-well capacity, zero blooming and lower power consumption.
OMNIVISION’s OVMed® product line includes 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 offers a wide range of resolution and frame rate combinations that can be selected based on the procedural requirements: 720 x 720 at 30 fps, 600 x 600 at 40 fps or 400 x 400 at 60 fps. The high signal-to-noise ratio of the image sensor results in sharper, crisper images with excellent color fidelity—so surgeons can see the most realistic images to better diagnose and treat disease.
