Compared to other materials, LTO is extremely temperature stable and robust. Therefore, the detectors do not require additional cooling by a Peltier element even at high temperatures.
Especially at low to medium modulation frequencies, they feature high detectivity and a good signal-to-noise ratio. With a specific detectivity of typically 4.0 E+09 Jones at 10Hz, they deliver a performance similar to that of more expensive thermoelectrically cooled semiconductor detectors.
