Geometric Resolution of 3.1 Megapixels Due to an Integrated MicroScan Feature
The MicroScan technology works opto-mechanical and is designed for permanent operation. Due to FPA detectors of the latest generation with (1,024 × 768) IR pixels, this technology allows for a quadruplication of IR measurement pixels. They show real temperature values but not interpolated pixels. This opens up several new fields of application. Old measurement tasks become more efficient and therefore, valuable working time and costs are saved. Large-scale or far-flung measurement objects can now be recorded in one, fast, precise and complete recording due to the unique MicroScan technology.
Unrestricted Operation of the Infrared Camera in Harsh Industrial Environments
The robust light metal housing (protection degree IP67*) provides reliable protection for the high sensitive optronics of the device. In addition, it guarantees trouble-free operation even in harsh industrial environments and keeps constant the excellent optical and metrological performance parameters of the device over a long service life. In this way a long-term and trouble-free operation of the VarioCAM® HD head is guaranteed. The usage of a high-quality LEMO connector technology ensures a high protection degree of the infrared camera even for computer-based network operations. For applications in extreme ambient conditions there are suitable protective housings available, for example made of stainless steel. These are optionally equipped with a cooling, heating or both.
Permanent Autofocus for Optimal Focusing
Constantly changing object scenes require manual or automatic refocusing activated by the user. The integrated permanent autofocus function facilitates this work. In case there is a scene change the camera automatically adopts fast and precise the optimal focusing.
High-precision Calibration of Infrared Cameras Enables for High Accuracy of Measurements
The infrared camera VarioCAM® High Definition is calibrated using special algorithms. The specially developed calibration algorithm, with more than just a few calibration curves, is used for compensation of temperature fluctuations. Therefore, highest measuring accuracy and repeatability even at changing environmental temperatures is ensured. The exceptional high measuring accuracy can be reached across a wide temperature range.
Detection of Minor Defects through High Thermal Resolution
The thermal resolution describes the process to dissolve slightest temperature differences and thus, can display this measurement value. The infrared cameras of the VarioCAM® HD series have a high thermal resolution of up to 0.02 K that helps to display even slightest temperature differences with accuracy. In combination with the high-performance lenses this helps to detect critical faults at an early stage and display these in excellent quality.
Comprehensive Range of Precision Interchangeable Lenses Enables for a Wide Range of Applications
Due to the comprehensive range of lenses for infrared cameras, a wide range of measurement objects is available, starting with micro thermography to telephoto lens applications for objects in a large distance. The optics of the VarioCAM® HD series were designed as uncompromising full lenses with an opening number of 1.0, highest transmission and transmission quality as well as low distortion.
Automatic Functions of the Infrared Camera
The numerous automatic functions, such as autofocus, automatic image optimisation, automatic hotspot display, automatic calibration range switch etc. enable a fast and effective operation.
