Short-wave infrared line scan camera to see what visible can’t
23 Jul 2020
The Teledyne DALSA Linea SWIR represents the latest development in InGaAs line scan cameras. The GigE Vision camera not only features a cutting-edge uncooled InGaAs line sensor with 40 kHz line rate, but also features from Teledyne DALSA’s vast line scan camera experience, making it ideal for industrial use. The series is available in 512 pixel (25 µm) and 1024 pixel (12.5 µm) resolutions, delivering high speed and high sensitivity SWIR images at a significantly lower price than areas scan based SWIR cameras.
The compact, lightweight and robust camera feature set includes cycling mode with multiple user configuration sets, making it possible to work with different light sources, lighting angles, exposure times, gains etc. for every line. With this technology a single pass with a single camera delivers many sets of information which is comparable to that of multiple cameras to enable capabilities such as multi-spectral material classification and surface inspection without the need for costly and complex hardware solutions while also reducing inspection time.
For scenes with very bright and very dark parts within the field of view, the Linea SWIR comes with a HDR mode extending the dynamic range of the camera significantly. As SWIR is invisible to the human eye, it is very difficult to estimate the dynamic range of a scene just visually, the HDR mode gives you the confidence to esure you capture all the information and maximising the ability to solve the most demanding applications.
The GigE Vision camera supports PTP (precision time protocol) making it easy to perform stereo line scan applications or applications requiring multiple cameras inspecting an object at the same time. For applications requiring more than just triggering via GigE, the powerful programmable I/O interface of the camera features 2 inputs and 2 outputs.
