L3CMOS14000KPA Microscopy Cameras/Microscope Cameras
Product Introduction
The L3CMOS series features C-mount USB3.0 microscopy cameras equipped with Aptina (onsemi) high-sensitivity CMOS sensors and onboard buffer architecture. Under 5 Gbit/s USB3.0 bandwidth, these cameras achieve more stable high frame rate transmission while reducing frame loss and jitter caused by burst data. Resolution coverage spans approximately 2.2–12 MP, suitable for educational, routine scientific research, and general microscopy documentation applications.
The built-in Ultra-Fine color processing engine performs demosaicing, auto exposure/gain control, one-click white balance, and color/gamma/contrast processing on the camera side, reducing host CPU usage while delivering natural and consistent color presentation. The housing features metal (aluminum alloy) CNC precision construction for durability and reliability, while included ToupView/ToupLite software and cross-platform SDK support (Windows/Linux/macOS/Android) facilitate system integration and secondary development.
