OmniVision Technologies, Inc. announced from MD&M Minneapolis that its OV6948 is the winner of the Guinness World Record for “The Smallest Image Sensor Commercially Available” with its size of 0.575mm x 0.575mm. Derived from this ultra small imager, the company also announced its OVM6948 CameraCubeChip–a fully packaged, wafer-level camera module measuring 0.65mm x 0.65mm, with a z-height of just 1.158mm.
OmniVision developed these innovative medical imagers to address the market demand for decreased invasiveness and deeper anatomical access. Additionally, these imagers can address the many challenges posed by reusable medical imaging equipment, including cross-contamination risks and inefficiencies due to high maintenance costs.
Utilizing a highly effective and economical wafer-level packaging technology, the OVM6948 is making the mass production of disposable medical imaging equipment possible. Additionally, this complete module can be integrated into a catheter or endoscope with a diameter as small as 1.0mm. With this camera’s small size and high 200×200, or 40 KPixel backside-illuminated resolution, high quality images can be captured from within the body’s narrowest blood vessels for neuro, ophthalmic, ENT, cardiac, spinal, urology, gynecology and arthroscopy procedures. Additionally, many space constrained dental, veterinarian and industrial applications can also benefit from the OVM6948’s advanced design.
The OVM6948 is the only ultra small “chip on tip” camera with backside illumination, which provides excellent image quality and better low-light performance to help reduce LED heat, along with improved sensitivity. It also allows for the use of superior lens technology over competing front-side illumination cameras in this class. Additionally, this color analog camera with OmniBSI+™ technology enables easy calibration in production and is reflowable with a 4-pin interface for simplified integration, which shortens time to market while reducing costs.
Other key features of this camera module include a wide 120-degree field of view and an extended focus range of 3mm to 30mm. Its image array is capable of capturing 200×200 resolution images and video at up to 30 frames per second, and its analog output that can transmit over 4 meters with minimal noise. The camera also offers low power consumption of 25 mW, generating less heat for better patient comfort and flexible procedure durations.
The OVM6948 is available now for volume production in the tray format, along with an evaluation kit. Additionally, this camera module will be demonstrated at OmniVision’s booth #1248, at the MD&M Minneapolis trade show October 23-24.
