MCT Photoelectromagnetic detectors

The PEM series detectors operate on the photoelectromagnetic effect in the semiconductors. The devices are typi-cally optimized for the best performance at 10.6 μm.

Example of D* vs Wavelength λ for PC Series HgCdTe Detectors. Spectral Characteristics of individual detectors may vary from those shown on the chart.
