EMIR Detector

EMIR has a HAWAII-2 FPA dedector manufactured by Teledyne. The HAWAII-2 infrared detector is a  HgCdTe  array of 2048 by 2048 pixels (18 µm/px) sensitive to IR light. The detector operates between 1 and 5 µm and optimized in the K band (2.1 µm) at cryoginic temperatures. The detector is divided into 4 similar quadrants of size 1024x1024 and in 32 channels each quadrant in order to read faster the whole frame.



Its main characteristics can be summarized in the following table:
