Lithium tantalate detectors have use in FTIR spectroscopy
The LT3111 series pyroelectric lithium tantalate (LTO) detectors feature a 7-µm-thick chip. Suited for Fourier transform infrared (FTIR) spectroscopy, the detectors do not require additional cooling by a Peltier element at high temperatures. They offer a specific detectivity of typically 4.0 E+09 Jones at 10 Hz.
