PEM series HgCdTe detectors datasheet P a g e | 1 09/11/2020 VIGO System S.A. reserves the right to change these specifications at any time without notification. www.vigo.com.pl PEM series 2.0 – 12.0 µm HgCdTe ambient temperature photoelectromagnetic detectors PEM series features uncooled HgCdTe photovoltaic IR detectors based on photelectromagnetic effect in the semiconductor – spatial separation of optically generated electrons and holes in the magnetic field. The devices are designed for the maximum performance at 10.6 µm and especially useful as a large active area detectors to detect CW and low frequency modulated radiation. These devices are mounted in specialized packages with incorporated magnetic circuit inside. 3° wedged zinc selenide anti-reflection coated (wZnSeAR) window prevents unwanted interference effects and protects against pollution. Spectral response (Ta = 20°C) Exemplary spectral detectivity, the spectral response of delivered devices may differ.
