product brief

• Miniature Camera Module Provides High-Quality Imaging for Disposable Medical Guidewires, Catheters and Endoscopes
• OmniVision OVM6948 CameraCubeChip® is a fully packaged, wafer-level camera module measuring 0.65 mm x 0.65 mm, with a z-height of just 1.158 mm, ideal for disposable devices operating from the smallest part of the anatomy.
• The camera module is derived from an ultra-small image sensor, the OV6948, winner of the Guinness World Record for “The Smallest Commercially Available Image Sensor*,” with a size of 0.575 mm x 0.575 mm.
• This complete module can be integrated into a disposable guidewire, catheter, or endoscope with a diameter as small as 1.0 mm.
• With this camera’s small size and high 200 x 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.
• 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 offers a compact, high-quality solution for disposable guidewires, catheters, and endoscopes, which are experiencing growing demand because of their ability to reduce cross-contamination risks, downtime inefficiencies, and costs associated with the repairs, preprocedural testing, and sterilization of reusable endoscopes. Benefiting from the sensor’s low power consumption of a mere 25 mW, less heat is generated for better patient comfort and flexible procedure durations.
• Other key features of this camera module include a wide 120-degree field of view and an extended focus range of 3 mm to 30 mm.
• Its image array is capable of capturing 200 x 200 resolution images and video at up to 30 frames per second, and its analog output can transmit over 4 meters with minimal noise.
