STEMMER IMAGING

The visible (400 to 700 nm) and the NIR (700 to 1000 nm) spectral ranges offer numerous applications. However, the SWIR spectral range (950 to 1700 nm) allows imaging of chemical features that are impossible to detect with lower wavelength bands. Another advantage is that SWIR can penetrate the surface of many materials with some microns, which makes the detection of features in your inspection object possible that might not work without SWIR.

Cycling mode implements a method to use various different user-controlled configurations. This means that you can work with different light sources, lighting angles, exposure times, gains etc. for every line. This way, a single pass with a single camera delivers a high amount of information which is comparable to that of multiple cameras or combinations of camera and frame grabber. With this feature, costly and complex hardware solutions can be avoided, since e.g. multiple illumination variants of the same object increase failure detection and production security. It can also reduce inspection time in cases where various illumination set-ups are mandatory to inspect one object.

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. SWIR is invisible to the human eye, making it very difficult estimating the dynamic range of a scene just visually, the HDR mode gives you the extra confidence to solve your application.

Precise time protocol (PTP) is an Ethernet protocol which allows the synchronization of several cameras as well as precise triggering via GigE without the need for a further trigger cable. This way, you can easily perform stereo line scan applications or applications that require multiple cameras at one inspection object at the same time.

The small and light-weight housing allows the design of compact camera solutions. The integration into existing systems with restricted space availability for machine vision components is simplified. The Linea SWIR cameras provide Power over Ethernet (PoE), making additional power supplies and power supply cables unnecessary. This not only saves space but also reduces the risk of failing components.
