This paper presents. In this paper the comparison of uncooled thermal and deeply cooled QWIP (Quantum Well Infrared Photodetector) detectors are briefly presented. Different types of QWIP detectors have been mentioned. The limits of detectivity both for thermal and photon detectors are discussed. Today, the significant progress in infrared technology is observed. It is due to increasing interest of infrared sensitive equipment, especially in the domain of uncooled devices, which are much chipper with satisfactory parameters. Such detectors are widely used for e.g.: thermal inspection, observation, and maintenance. On the other hand very precise quantum detectors are still under development. The most efficient quantum detection based on MCT (HgCdTe) now has a competitor which uses traditional wide band gap semiconductor (AlxGal-xAs/GaAs), where the carrier excitation takes place in quantum well. Both resposivity and detectivity of quantum infrared detectors is a Junction of wavelength, while it does not depend on spectral range for thermal ones.
