SR557MMA Scientific Camera
Product Introduction
The SR series addresses ultra-high resolution scientific imaging requirements, utilizing the VPS2163A high-precision CMOS image sensor with single-frame capabilities reaching 20,480 × 27,200 (≈ 557 million pixels) and 0.5 µm pixels, suitable for cell morphology, biological tissue structure, semiconductor/wafer defect detection, microstructure metrology and other demanding applications.
The camera provides USB3.0 data interface with 8/10-bit output formats, built-in buffering ensuring stability for large pixel full-frame acquisition. Full-resolution complete image typical frame interval is approximately 6 s (dependent on acquisition and storage conditions).
The SR series integrates efficient thermal control systems with TEC cooling, achieving sensor operating temperatures approximately 40 °C below ambient (ΔT ≈ 40 °C), effectively suppressing dark current and improving consistency during extended acquisition periods. The compact design supports free-running acquisition and external triggering, compatible with various lens interfaces. Bundled with ToupView and cross-platform SDK (Windows/Linux, C/C++/C#/Python) for convenient system integration and secondary development.
