Advanced high-speed infrared camera offers even more performance when recording thermal images of extremely fast thermal processes

For some years now, the ImageIR® 5300 has been the top model in terms of temporal resolution within the high-end camera series ImageIR® from InfraTec. This special position is attributable to its detector. Its sensitive elements are larger than those of conventional detectors and are arranged at a distance of 30 µm. As a result, the model has an enormous thermal sensitivity of 0.015 K. This excellent signal-to-noise ratio is accompanied by integration times of less than 10 μs for technically relevant object temperatures. Thereby frame rates of up to 105 kHz can be realized. For this reason, the infrared camera is predestined for the solution of measurement and testing tasks, in which extremely rapid thermal processes are to be captured and recorded.

An example of this is the analysis of combustion processes. Others can be found in various areas of research. Questions concerning aerodynamics and flow technology in the field of aerospace and applications, in which laser technology is used, are linked to such high frame rates.

High temporal resolution also plays a role in the analysis of wearing processes within the automotive industry. In this area, the ImageIR
® 5300 also demonstrates the strengths of its concept. The automated Thermal Rotate Check (TRC) IR rotation test system from InfraTec provides the framework for this. As part of this, the infrared camera supports the precise analysis of fast rotating components such as tyres and brakes. The results of such analyses provide important information about how well the test objects withstand continuous operation, which signs of wear are present and how serious they are, and which mechanisms cause them.

The improved frame rate of the ImageIR
® 5300 ensures that users can use this model to solve a wide range of tasks in industry and science. Their modular design consisting of an optics, detector and interface module makes it easy to adapt to a wide variety of measurement scenarios. The integrated process and trigger interface enables the infrared camera to be synchronized precisely with external processes for analyses – and in the case of the ImageIR® 5300, these processes can readily be connected at maximum speeds.
