OMNIVISION’s OCOVA wafer-level camera module is the first CameraCubeChip® module with Nyxel® technology and features the industry’s smallest pixel size of 2.2 microns. The OC0VA expands our family of the industry’s smallest GS imagers by providing a VGA resolution option with the best NIR performance in a global shutter device. Existing VGA global shutter devices have low near-infrared (NIR) quantum efficiency (QE) and high modulation transfer function (MTF) degradation, which requires a stronger light source with high power consumption and low performance. The OCOVA features OMNIVISION’s PureCel®Plus-S stacked pixel architecture and Nyxel® NIR technology to enable optimal performance and precision along with industry-leading QE and excellent MTF for sharp, accurate images in machine vision and 3D sensing applications.
The OC0VA is ideal for a wide range of consumer and industrial machine vision and 3D sensing applications that need a global shutter to avoid motion blur, along with top NIR performance that reduces system power consumption by requiring less IR LED illumination in low- and no-light conditions. It combines image sensor OG0VA with image signal processing and optics into a compact wafer-level camera module. The wafer level module’s low light sensitivity is excellent, with significantly lower gain than the industry’s typical 3.0 micron pixel size for an improved signal-to-noise ratio. Target applications include facial authentication and eye tracking in smartphones and notebooks, as well as imaging for AR/VR headsets, drones and robots.
The OCOVA’s high MTF enables sharper images with greater contrast and more detail, which helps to enhance machine vision decision-making processes. Additionally it features a high QE of 40% at 940 nm and 60% at 850 nm. This industry-leading QE enables devices to see farther and better in low- and no-light conditions, which allows designers to use less IR LED light and achieve lower system-level power consumption. For AR/VR headsets, this reduces heat generation, while industrial and robotics applications can use fewer IR LEDs for lower system cost, or use the same number to achieve a greater image detection range.
