U3CMOS Series
Product Introduction
The U3CMOS series represents C-mount USB3.0 CMOS cameras featuring Aptina (onsemi) high-sensitivity, low-noise image sensors designed for laboratory research and industrial inspection applications. Through 5 Gbit/s USB3.0 high-speed links, these cameras achieve high frame rate and stable image/video output. Resolution coverage spans 3.1–18 MP with aluminum alloy CNC precision construction for durability and long-term deployment capability.
The built-in Ultra-Fine color processing engine completes demosaicing, auto exposure/gain, one-touch white balance, and color/gamma/contrast processing within the camera, delivering more natural color presentation while reducing host CPU utilization. Products include ToupView/ToupLite software and cross-platform SDK support (Windows/Linux/macOS/Android) for seamless system integration and secondary development.
