These discrete sensors can be configured with different kinds of lenses, resulting in a variety of field of views (FOV). Furthermore, we do customer specific optics on request. The small dimensions and the very low power consumption makes the HTPA series very attractive for handhelds and battery powered solutions. The sensor chip contains next to the sensor elements integrated low noise chopper amplifiers and low pass filters + temperature reference, voltage reference and an analogous output. Some types also provide an digital output, powered by their integrated 12bit ADC.
