The Serval fulfils a growing demand for ruggedized and reliable thermal cameras for industrial imaging applications without the need for third-part
All objects with temperature above the absolute zero (-273,15 °C or 0 K) emit heat radiation. The hotter the object, the more radiation is emitted. This radiation is also called infrared radiation since most of it is emitted in the infrared spectral band of the electromagnetic spectrum.
(Infrared) thermography is a non-contact imaging and temperature measuring technique. An infrared imager is used for detection and display of radiation within the infrared part of the electromagnetic spectrum.
The detector of the infrared imager detects and displays only the variations of radiation intensity. This results in an image where you can see the temperature variations of the scene.
The convertion of the collected radiation into temperature measurements is done internally in the infrared camera and/or via external online or postprocessing software. This convertion is a complex process where we use well know physical formulas and the radiation properties of the object, its surroundings and the atmosphere.
After all this processing your infrared camera generates an image where you can read the measured temperature, a so-called Thermogram.
Thermography is widely used in applications where contact-thermometry cannot be used to measure temperature. Various R&D applications (like medical, aerospace and remote sensing) use thermography as a non-contact temperature measuring and visualization technique. In the industry, NDT, predictive maintenance and condition monitoring of installations and equipment often use thermography. And thermography is even used in the Safety & Security market, where it is often used by firefighters or for perimeter control.
For thermography with uncooled LWIR bolometer cameras we offer our Gobi-640 and Serval series. Our Gobi comes in a high 640 x 480 (Gobi-640) resolution with a pixel size of 17 μm. The Gobi thermal camera series is available in two different sensitivity levels. We offer a 50 mK NETD and a 75 mK NETD version. The lower the NETD, the smaller temperature difference you can detect and measure.
Our Gobi cameras are thermally calibrated in-house. We guarantee a temperature measurement accuracy of +/- 2 °C or +/- 2 %, whichever is the highest (ambient conditions apply).
Our cooled thermal cameras, the Tigris-640, are highly sensitive at approximately 25 mK NETD. Working in snapshot mode at high frame rates, you can capture very clear thermal images of fast moving objects. In case the standard framerate is still too low, you can reduce the window of interest which increases the frame rate further. The Tigris-640 comes with GigE Vision and cameralink interfaces.
