Q1 : Which specific applications are the standard and optional factory filters suitable for?

Standard LPF390H (400–1800nm): Covers visible light and the full short-wave infrared range, suitable for fruit and vegetable inspection, general material sorting, visible and infrared comparison experiments, and broad-spectrum material spectral analysis. Optional LPF1000H (1030–1800nm): Filters out all visible light, keeping only the infrared band, suitable for silicon wafers, photovoltaic EL inspection, smoke and security monitoring, and pure infrared specialized spectral experiments.

Q2 :How to choose among the four cameras in the SWIR035A series?

All four cameras are equipped with Sony IMX992 SenSWIR InGaAs sensors, with identical pixel size, resolution, and cooling, so the image quality is exactly the same. The only differences are in data interfaces and frame rates. Among them, the SWIR035AU camera is suitable for labs, small desktop setups, and short-distance transmission—plug and play. The SWIR035AG camera transmits data via Ethernet, supports long-distance transmission, and is ideal for industrial long-distance wiring, automated production lines, and material sorting. The SWIR035ACXP offers high-bandwidth stable output, making it perfect for high-speed laser monitoring and high-precision semiconductor online inspection; it requires a dedicated CXP capture card. The SWIR035ACL camera has a high bandwidth ceiling, compatible with traditional vision acquisition systems and research high-frame-rate acquisition platforms, and comes with CLView software.

Q3 : Which scientific research scenarios is the SWIR035A suitable for, and how do its hardware and software meet data acquisition needs?

Applicable research scenarios: Measuring continuous/pulsed laser spot profiles, near-infrared fluorescence imaging in biology, material transmission/reflection spectroscopy, and long-term low-light imaging experiments. On the hardware side for the SWIR035A series cameras: freely switch between dual gain modes; after hardware ROI cropping, can reach up to 8000fps to capture transient laser signals; up to 60s exposure with TEC temperature control for drift-free long experiments; 512MB buffer to prevent frame loss in high-speed data streams. On the software side: AttosView comes with profile lines, pixel intensity readout, timestamps, and 12 customizable dark frame corrections; ACL models include CLView acquisition software. On the development side: full-platform SDK supports C/C++, Python, Java, C#, and natively works with LabVIEW, MATLAB, and Micro-Manager, allowing research data to be directly exported for modeling and spectral fitting.
