Paper Abstract

In order to fulfill the special requirements of space application on the spectral response properties and curve uniformity of multielement PC HgCdTe device, many measures have taken to improve the uniformity of multielement spectral response curve. We have deposited anti-reflecting coating on the surface of multielement HgCdTe detector chip, and the problem of deposition has been solved, better anti- reflecting coating has been prepared. The spectral response measurement results confirm that the spectral properties and the curve uniformity of multielement PC HgCdTe detector are improved obviously after depositing anti-reflecting coating, and fulfill the special requirements of multispectral scanner used for space application.
