SR Series
Product Introduction
The SR series is designed for ultra-high resolution scientific imaging, utilizing the VPS2163A high-precision CMOS image sensor. It captures images at 20,480 × 27,200 (≈ 557 megapixels) with a 0.5 µm pixel size, ideal for cell morphology, biological tissue structure, semiconductor/wafer defect inspection, and microstructure metrology applications.
The camera features a USB 3.0 interface with 8/10-bit output formats and built-in buffer to ensure stable acquisition of large pixel images. Typical frame interval for full-resolution images is approximately 6 s (depending on acquisition and storage conditions).
The SR series incorporates an efficient thermal control system with TEC cooling, reducing the sensor's operating temperature by about 40 °C below ambient (ΔT ≈ 40 °C). This effectively suppresses dark current and enhances consistency during long-term acquisition. The compact body supports both free-running and external triggering, compatible with various lens mounts. It comes with ToupView software and cross-platform SDK (Windows/Linux, C/C++/C#/Python) for easy system integration and custom development.
