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.
Storage of Fast Infrared Sequences with up to 240 Hz
In case of sudden temperature changes, the infrared camera VarioCAM® High Definition provides a sub-frame modus (“subwindowing”) that is usually only found in cooled infrared cameras. The VarioCAM® HD series allows recording of infrared sequences with frame rates up to 240 Hz. In order to reach such high frame rates, each time a defined section of the detector is being read.
