Hamamatsu Corp.’s thermopile detectors offer high sensitivity to mid-infrared wavelengths, making them suitable for gas analysis and temperature distribution measurements.
The T11262-01 single-element thermopile is sensitive to 3- to 5-µm wavelengths, a spectral range where gases (carbon dioxide, carbon monoxide, sulfur oxides, etc.) have signature spectral emissions. The T11722-01 dual-element thermopile is designed for measuring carbon dioxide concentrations. It allows simultaneous measurement of carbon dioxide at 4.3 µm and a reference at 3.9 µm.
The T11263 series linear arrays offer 16 or 32 channels, and the T11264-08 is an 8 × 8-channel array. The arrays operate with 5-V supply voltage, have an integrated CMOS signal processing circuit and are sensitive to mid-IR wavelengths from 5 to ~20 µm. They are appropriate for measuring the temperature distribution of objects.
