In many fabrication shops the ambient temperature on, near, and in between machines varies greatly. That can be counter-productive to gathering data with a camera sensor. The new 61 megapixel (MP) industrial camera hr455xXGE-T in mono or color from SVS-Vistek (Gilching, Germany) with TEC cooling ensures stable working conditions for the sensor, even when external conditions are in flux. This, in turn, results in enhanced and reproducible image quality, which is especially crucial in display inspection, semiconductor and electronics production, and other demanding applications.
Even minor fluctuations in the temperature of a camera sensor have a detrimental effect on image quality, thereby rendering subsequent image analysis more challenging. An increase in sensor temperature, for instance, results in a decline in the signal-to-noise ratio and a change in the sensitivity of the sensor. The spectral sensitivity varies in response to temperature, exhibiting different changes for different wavelengths. Consequently, temperature-dependent calibration is essential for applications with heightened requirements. The new hr455xXGE-T employs thermoelectric cooling (TEC) which serves as an effective solution to the mentioned challenges. This maintains a constant operating temperature for the sensor, even in the presence of fluctuating external conditions. The resulting temperature stabilization ensures the reproducibility of results.
SVS-Vistek custom designed the TEC concept in the latest hr455xXGE-T model, which is specifically optimized for large-area sensors. Among other things, this involved the development of a new housing design incorporating integrated ventilation. The SVS range of temperature-stabilized cameras has been extended to include a new variant, which now also supports high-resolution sensors in the visible spectral range in addition to the SWIR cameras up to 5 MP already available on the market.
The hr455xXGE-T is equipped with a powerful 10GigE interface, that enables rapid and dependable data transmission even at elevated production speeds, due to its high bandwidth. The initial resolution of 61 megapixels ensures the detection of even the minutest errors.
