Brilliant Down to the Smallest Detail

InfraTec’s (Germany) VarioCAM HD head series of thermal imaging cameras offer high resolution performance based on the latest generation of uncooled microbolometer FPA detectors . With up to (1,024 × 768) IR pixels, the largest detector in its class, VarioCAM HD head delivers brilliant 16-bit thermography images.  Thanks to the opto-mechanical MicroScan unit, IR image formats with a geometric resolution of 3.1 MegaPixels are possible. With this technology, the thermal radiation of the object being measured strikes a rotating germanium disc and is deflected through a tumbling motion of the disc according to a precise pattern. As a result, the measurements are depicted thermally without gaps, hence the detector’s effective fill factor is 100%. The geometric resolution rises to (2,048 × 1,536) IR pixels, which represents genuine temperature measurement values. In this way, detailed thermograms that ensure exact recording and measurement of complex structured measurement objects are created. The VarioCAM® HD head gains markedly in image sharpness and reproduction quality compared to a purely software-based approach to increasing the number of pixels, which in contrast produce only interpolated image points. Measurement errors due to geometry can be avoided reliably. In combination with an excellent thermal resolution of up to 20 mK, the thermal imaging cameras are suitable for sophisticated fixed mount stationary measurement and test tasks from production, quality assurance, process optimisation, research and development as well as aerial imaging.

Applications at such a high technological level are often combined with adverse environmental conditions. Therefore, the complete series is equiped with a shock-resistant light metal housing that keeps out dust, dirt and waster, and, if desired, fulfils IP67 criteria. The robust design and compact housing dimensions allow problem-free installation in the toughest of process environments. If the surrounding temperatures are prone to reaching extremely high or low values, there is a suitable stainless steel protective housing with optional cooling or heating provides additional protection available.

Moreover, a look inside shows how adaptable the VarioCAM HD head is. With GigE Vision and GenICam, the camera series supports industry-wide standards for data transfer and image processing. As a result, each model is not only usable through the efficient and convenient thermography software IRBIS 3 from InfraTec, but – based on these standards – also allows easy integration into existing system environments.

As a result of many years of cooperation with Jenoptik, InfraTec offers a wide spectrum of high-quality optics for the VarioCAM HD head. For example, users can record tiny structures of up to 17 μm with the single microscope objective. This optic is just as impressive as the additional super-wide angle or telescopic lenses with light intensity of f/1.0 and multiple anti-reflective coatings. In this way, the thermography system ensures a maximum of flexibility and supports a constant high measurement quality with the most varied tasks.

There are innumerable possibilities to make use of the VarioCAM HD’s  great features. For even in their stand-alone variants, the series’ models are powerful thermography systems. The versatility of the thermal imaging cameras truly comes to light in the individual assembly of a total package that is adapted to the respective measurement and test conditions on site.

Aside from the fast infrared precision optics, there are modules and extensions of the IRBIS 3 software family and excitation sources and controllers that are suitable for continuous operation, that round off the extensive array of accessories. This means that there are a multitude of possible applications for the user. This ranges from active thermography to micro-thermography and aerial thermography up to object monitoring. Moreover, the VarioCAM HD head is a central component of many key-ready automation solutions from InfraTec.
