Q1 : What imaging advantages does this camera series offer for wide-field monitoring and scientific research?

The SWIR151B series camera has a 1.3MP (1280×1024) resolution and features large 15μm × 15μm pixels. This combination of ‘high resolution and large pixels’ means it can capture rich image details while also gathering a lot of light, making it ideal for low-light imaging. The camera sports a 1.5″ sensor, which is quite large and offers a wider field of view, allowing you to capture more information in a single shot

Q2 : How to choose among the three SWIR151 interface models (BU/BG/BCL)?

The SWIR151B camera series all come with high-performance InGaAs sensors, with identical pixel size, resolution, and cooling. The differences are mainly in transmission interface, frame rate, and maximum exposure. SWIR151BU (USB3.0): Full-frame 200fps, exposure 16μs~1s; plug-and-play with no capture card needed, ideal for desktop lab spectroscopy and small offline inspections. SWIR151BG (10GigE): Full-frame 200fps, exposure 25μs~5s; long-distance transmission over network cables up to 100m, suitable for mid-to-high-speed long production lines, plastic sorting, and fruit & vegetable sorting. SWIR151BCL (CameraLink): Full-frame 200fps, exposure 16μs~1s; comes with CLView software, fits traditional high-frame research platforms and pulse laser capture.

Q3 : How can external hardware triggers and dark frame correction be called through the SDK?

External Trigger: The SDK lets you set trigger delays and the number of consecutive frames to capture at once, and it syncs the timing when using multiple pipeline sensors. Dark Field Correction: First, take multiple dark frame templates in the AttosView software and save them to the camera hardware. The SDK can then call the relevant interface to enable it with one click, removing long-exposure fixed noise.
