This year Heimann Sensor announces the new HTPA64x62 sensor. The sensor is fully pin compatible to the existing HTPA32x31. The HTPA series provides very low time constants of the elements, low noise amplifiers, serial peripheral interface and a high frame rate. Some types also provide an internal ADC. For improved sensitivity several finite element simulations were done. We examined - Different pixel designs - Membrane shapes - Number of thermopiles - Influence of filling gas...
