digitalline-scanfor the glass industry

The PI 450i G7 is a high-performance infrared camera designed to meet the needs of both researchers and process engineers. The PI 450i G7 thermal imager is a versatile, high-performance infrared camera that supports remote infrared temperature measurement applications for research and process control applications. This versatile thermal imager supports a high VGA resolution and image quality in its standard configuration, measuring the full temperature range from -20°C to 900°C. The camera can be calibrated for high-temperature infrared measurements with a temperature range of up to 1500°C. The infrared camera uses a 382 x 288 uncooled microbolometer infrared detector to create thermal images. Superior radiometric measurement characteristics and high image quality define the Precision Line of Optris. For the accurate measurement of temperatures, the emissivity of glass is a key factor. It depends on various influences and must be considered according to the application. The special G7 spectral range of 7.9 µm matches the glass material’s highest emissivity, which eases remote temperature measurement as the spectral region of reflectivity and transmissivity are minimized. In addition to reduced reflection issues, another advantage is the decreased angle dependency of glass surface emissivity within this wavelength range. As a result, surface temperature can be measured independently of reflection, even at inclined viewing angles. Unlike other infrared cameras with smaller pixels, the optimal pixel pitch size of 17 µm for long-wavelength infrared radiation allows a small measurement field of view (MFOV) of just 3 x 3 pixels.
