The quantum dot SWIR camera HJK-SWIR from HJKIR is a lower-cost imager for industrial and scientific use, responding from 400 to 1700 nm (VIS, NIR and SWIR) with a peak at 1550 nm. It provides 640×512 resolution (15 µm pitch), a global shutter, frame rates up to 100 Hz, a built-in single-stage TEC and a Gigabit Ethernet interface, all in a compact 240 g body drawing 3 W on average.
Machine vision integrators and research labs use this quantum dot SWIR camera when they need imaging from VIS to SWIR at a lower cost point.
Overview: Compact quantum dot SWIR camera with 640×512 resolution, 400-1700 nm response, TEC cooling, C-mount lens interface and a Windows and Linux SDK.
