Attention to Sources of Error On-Glass Measurements

On-glass measurement with infrared thermal imaging

In contrast to the visible light spectrum, glass – being looked at with an infrared camera – generally appears in a non-transparent way, since its transmission factor is very low in the infrared range. Therefore, it is mostly possible to determine the temperature of glass without making specific arrangements, even though in case of thinner glass layers and high temperatures behind glass, radiation of transmission can lead to distorted thermographic measurement results. The glass temperature then would be disproportionally high.

Precise Glass Measurement with Thermography Through Spectral Filters

Through-glass measurement with infrared thermal imaging

The problem of glass measurement can be solved by applying InfraTec’s infrared camera systems of its high-end camera series ImageIR®. These are possible to be equipped with spectral filters being deployed in a filter wheel. Filters will be individually adjusted according to the specific glass of the customers. On the one hand, these filters allow measuring the surface temperature of glass without any impact of the transmission radiation of objects behind glass. On the other hand, measurements of objects with high temperature behind glass can be carried out without having an influence on the glass surface temperature. Since the infrared camera’s filter wheel is power-driven and remotely controllable, switching between both modes can be ensued by a keystroke at the control computer.

  • Further information about HDR-function

    HDR – Simultaneous Mapping of Wide Temperature Ranges

    The High Dynamic Range (HDR) function of the Infrared ImageIR® camera series enables measurement scenarios with extremely different temperatures to be recorded continuously. When recording in HDR mode, multiple thermograms with different integration times and different filters are recorded quickly in succession and compiled into an overall image with a high dynamic range. The measuring range can span up to 1,500 K. Users obtain high-contrast images in a wide temperature range characterized by high measurement accuracy.

    HighSense – Always the Optimal Camera Setting

    Thanks to HighSense, ImageIR® users have the option of setting up individual measuring ranges based on the factory calibration that best suit the respective task. The software also offers the possibility of storing a large number of such areas clearly arranged. Individually named and permanently stored, the operator can quickly access them. The same applies to changing, renaming and deleting profiles. HighSense is available for different camera models of the ImageIR® series. This function can optionally be added to systems already delivered.

    Further information about the 10 GigE technology

    10 GigE Interface for a Strong Increase in Output

    The 10 Gigabit Ethernet interface of the high-end camera series ImageIR® opens this extremely fast transmission standard with a NIC specially developed by InfraTec. This works with optical or electrical transceiver modules that are easy to change and are called SFP+.

    Different 10 GigE fiber SFP+ transceivers allow transmission ranges of up to ten kilometers with the same low sensitivity to electromagnetic interference. A corresponding standard SFP ensures backward compatibility with the conventional GigE interface. This combination allows the ease of use of the cameras with the 10 Gigabit Ethernet interface in existing systems - though at a reduced transmission rate.
