At modulation frequencies in the kHz range, the pyroelectric material DLaTGS (deuterated L-alanine doped triglycine sulphate) achieves up to three times higher detectivity compared to lithium tantalate. This makes DLaTGS detectors the gold standard for use in Fourier transform infrared spectrometers (FTIR). However, the higher detectivity requires a better thermal stabilization of the detector. Besides […]
