SS21MPA-U3-CXP Scientific Camera
Product Introduction
The SS series is built on GSPRINT high-frame-rate global shutter sCMOS sensors, balancing high resolution with high frame rates, specifically designed for industrial inspection, high-speed imaging, and scientific experiments in high-dynamic scenarios. The series covers 2–21 MP multiple specifications with 4.5 µm pixels, typical spectral response 300–1100 nm, effectively suppressing motion distortion and trailing.
The cameras provide USB3.0 and CoaXPress (CXP, model-dependent) high-speed links, built-in 1 GB image buffering, supporting 8/10/12-bit output. Through ROI/windowing and 2×2 binning (model-dependent), frame rate and throughput can be further enhanced. Supporting free-running, software/hardware triggering and multi-camera synchronization, suitable for timing coordination with external illumination, motion platforms and other experimental equipment.
Bundled with ToupView and cross-platform SDK (Windows/Linux, C/C++/C#/Python), facilitating system integration and secondary development. Some models provide TEC cooling versions for reducing dark current and improving low-light/short-exposure contrast.
