sNIRII640B-U3 Scientific Camera
Product Introduction
The sNIRII series targets cutting-edge research applications in the 900–1700 nm (NIR-II) spectral range, employing China-made InGaAs image sensors that combine high sensitivity with low readout noise, suitable for in vivo near-infrared imaging, biological fluorescence detection, materials/device characterization, and other scenarios. The typical configuration provides 640×512 resolution with 15 µm pixels, maintaining excellent contrast and detail even under low-light conditions.
To suppress dark current and thermal noise, the system features TEC cooling with closed-loop temperature control, reducing the sensor operating temperature by approximately 40 °C below ambient; combined with anti-fogging optical design, this ensures stable and clean imaging under low temperature and long exposure conditions.
The camera provides USB3.0 and 10GigE (model-dependent) high-speed data links, supporting 8/16-bit data output with built-in buffer to ensure link stability during high-speed acquisition. Acquisition modes include free-running, software/hardware triggering, facilitating synchronization with lasers, light sources, motion/stepper platforms, and other research equipment. Complete with ToupView and cross-platform SDK (Windows/Linux, C/C++/C#/Python) for system integration and secondary development.
