Recently, the lasers operating at 2-5μm have been expected for applications of science, industry, medical science etc. because of “eyesafe”. This paper reviews the Midium Wavelength InfraRed (MWIR) detectors covering the wavelength range 1.0-6.0μm (λ < 1.4 m: “eyesafe” spectral region). Most recent efforts in the technology of MWIR detectors have been on higher operating temperature making more covenient to use. These detectors are discussed for three wavelength regions: 1.0-2.0, 2.0-3.0, and 3.0-6.0μm.
