Smart and Unique Performance Features
Adjustable Focus Via Software
The VarioCAM® HD features a motorized focus adjustment (manual or automatic) controllable via software. By moving the actual sensor position inside the camera, optimizing the focus on the object can be done remotely without direct access to the camera.
3.1 Megapixel Resolution Thanks to MicroScan mode (available on the 900 series)
The MicroScan unit works opto-mechanically and is designed for continuous operation. With the latest generation of microbolometer detectors it enables in the format (1,024 × 768) IR pixels a fourfold increase of the measuring points to (2,048 × 1,536) IR pixels. These represent real temperature measurement values and not interpolated image points. The significantly higher geometrical resolution not only results in qualitatively higher images, but allows access to numerous new applications. Furthermore, proven measuring tasks can be solved even more effectively. The MicroScan unit often allows extensive or remote measurement objects to be captured quickly, precisely and entirely with just one shot. This saves additional lenses, valuable time and offers a further benefit: The MicroScan unit enables a filling factor of 100 %. This means that the system ensures a continuous measurement of the temperatures on the depicted measuring object.
All-in-focus Thermal Imaging
The innovative EverSharp function allows all objects in the image scene to be brought sharply into focus, regardless of how far these are from the camera and which lens is used. Special algorithms ensure an automatic combination of several images with different focusing (multifocus images). In the resulting thermal image, a result from up to ten individual exposures, all object structures are thus sharply displayed so that the entire scene can be displayed and measured with the highest possible accuracy. The quality of the images depends entirely on the depth of focus of the lens used or the distance of the measuring objects from the camera. This means that the operation of the thermal imaging camera is even more convenient for the user.
Real-time Storage on SDHC Card
Recording dynamic scenes event-driven or timecontrolled at full speed and all temperature data – this is possible at any time with the camera’s internal real-time storage on SDHC card. In this process, radiometric data is stored in IRB format (infrared image format), which can be processed and analysed efficiently with the IRBIS® 3 evaluation software afterwards. Consecutive numbering of the single frames within the sequence and storage of timestamps in the header ensure an exact time-based assignment of the thermal image data. The data can also be recorded as PNG or AVI files.
High-speed Image Storage
Operation of the VarioCAM® HD in so-called subframe mode (sub-windowing) is provided for higher refresh rates. This mode enables the time or actioncontrolled recording of complex thermographic ces with refresh rates of up to 240 Hz. For this purpose, one defined section of the detector is read out at a time and transferred by means of GigE-Vision.
Designed for stationary use in industrial or lab environments
The VarioCAM® HD head is compatible with GigE-Vision and GenICam by default and has digital inputs and outputs. Through their modular design and the compact light metal housing they are particularly predestined for stationary use in harsh process environments as well as for computer-assisted laboratory tasks.
Camera housing: the very robust light metal housing is available with the protection degree IP67. In conjunction with protection degree preserving LEMO® connectors, it is excellently suited for use in harsh industrial environments. For applications under extreme environmental conditions, suitable protective housings are also available, e.g. made from stainless steel, which can optionally be equipped with a cooling and heating system.
Lens : the broad range of super wide-angle lenses, telephoto lenses and microscopic lenses provides the camera system with a high degree of flexibility. Every single lens with high luminous intensity (f/1.0) and its special calibration supports a constantly high measurement quality for the most varied tasks.
Tripod adapter on the bottom of the camera: the standard ¼” photo thread allows the use of standard tripods and adapter systems.
4 Thread for alternative mounting of the housing: a total of four threaded holes allow axially rotated mounting the camera by 90°.
GigE Vision Interface: (LEMO®-socket, 8-pin) Transmission of data fast and securely over distances of up to 100 m – this is the task of the GigE-Vision interface. In addition, the camera can be controlled remotely and supplied with current via Power over Ethernet by accessing this interface.
Trigger and process interface: (LEMO® socket, 14-pin) The integrated trigger and process interface guarantees precise, repeatable triggering via two bidirectional digital channels and two analogue outputs. It is connected via a Breakout box, which provides additional connections for power supply, video output (FBAS/PAL/NTSC) and RS232.
USB and HDMI connection: an HDMI and USB connection can be used for the digital output of video signals in high quality and for access to the optionally integrated large thermographic image data memory. These connections are fitted behind a cover for preserving the protection degree in harsh operating conditions.
Research and Development
Whoever develops new products pays attention to every detail from the start. During the recording of even the smallest structures, you effectively avoid measurement errors due to geometry. The acquired data with a measurement accuracy of one percent meet the highest demands. You safely transfer the thermal images in your measuring environment via the GigE interface in the image format of up to (2,048 × 1,536) IR pixels at a frequency of up to 240 Hz. In addition, you adapt the VarioCAM® HD perfectly to your measuring task. The wide range of lenses ensures a high degree of flexibility when you are handling different sized measuring objects and variable operating distances.
Microthermography
Complex electronic components are becoming increasingly powerful and smaller. For this reason, precision plays a crucial role during their development. The VarioCAM® HD allows you to analyse extremely small structures of up to 17 µm, which appear consistently sharp thanks to the EverSharp function, and to determine their temperatures exactly. The detector resolution of (1,024 × 768) IR pixels opens up adequate room for you to record your component reliably with sufficient, geometrical resolution. Thus, you obtain results with a high level of measurement accuracy.
Process Optimization
The continuous measurement in production processes places the highest demands on your devices. The compact light metal housing with IP67 of the VarioCAM® HD protects your camera even in harsh industrial environments. High-quality, protection class preserving LEMO® connectors ensure the transfer of the camera data. The GigE interface ensures fast and secure transfer up to 240 Hz in your system environment. The direct connection of the process interfaces to the special software IRBIS® 3 process allows your data to be integrated into the process environment.
Non-destructive Testing
The combination of repeatable triggering and high thermal resolution predestines the VarioCAM® HD particularly for nondestructive testing. Firstly, you create thermal images via external signals, transmit temperature-dependent signals simultaneously and thus synchronously control your test process. Secondly, the thermal resolution of up to 0.02 K ensures noiseless reproduction of the smallest temperature differences. The IRBIS® 3 active thermography software, which is adapted perfectly to the thermal image camera, supports the evaluation and display of the corresponding results with its complex evaluation algorithms.
Building Thermography
The unique geometrical resolution of the VarioCAM® HD of up to 3.1 Megapixels enables significantly more efficient analyses, particularly of large objects. You detect even the smallest structures, reduce the number of your individual images and thus save valuable time. The combination with a high thermal resolution ensures additional flexibility even under unfavourable heat flow conditions. With FORNAX 2 plus you no longer have to wait for days with the appropriate weather, but instead you can measure regardless of the time of year even in the case of slight temperature differences. The large 5.6″ colour TFT display is ideally suited for the initial check of your recordings on site.
Airborne Thermography
Do you want to inspect overhead electrical power lines, pipelines or industrial plants from the air? Or check large areas for energetic and material environmental pollution? Then the high-resolution VarioCAM® HD head is your choice. Integrated in gyro-stabilised platforms, so-called gimbals, the camera reliably records large-scale areas. You can determine and synchronously save the GPS coordinates from the camera location for each thermal image. In this way, you efficiently plan and effectively check from the air. The large range of interchangeable lenses also helps you to solve your measuring task.

The versatile range of precision interchangeable lenses of the VarioCAM® High Definition model series ensures maximum flexibility during their use. Possible measurement and inspection tasks include microthermography as well as telephoto applications for measuring objects at great distances. In this wide application spectrum, the lens design of the VarioCAM® HD camera series has proved to be an uncompromising, athermalised full lenses with the aperture f/1.0, highest transmission and quality as well as low distortion. Thus, the camera ensures simple handling, very fast operational readiness and extremely accurate measurement results as well as consistent image sharpness even in the event of widely varying environmental temperatures. A special, highly resistant DLC coating protects the optically active surfaces of the lenses even under harsh conditions. Extensive measuring objects such as photovoltaic systems can also be thermographically measured reliably and efficiently, such as objects requiring safety distances, as in the case of highvoltage installations. When changing a lens, this is detected automatically by the camera and the stored calibration data is loaded.
