The devices aretypically optimized for the best performance at 10.6 µm. ThePEMI devices have been optically immersed to high refractiveindex GaAs hyperhemispherical (standard) or hemispherical(option) lenses. The detector includes active element based on(HgCdZn)Te band gap engineered with selected composition anddoping profiles, and miniature permanent magnets to producemagnetic field.The PEM detectors are well suited for heterodyne detection of10.6 µm radiation. Exhibiting no flicker noise, they can be at thesame time used for detection of CW and low frequencymodulated radiation in the whole 2 to 11 µm spectral range.Custom detectors such as single elements of various sizes,quadrant cells and multielement arrays, various specializedpackages and connectors are available upon request.CHARACTERISTICS UNITS PEM-10.6 PEMI-10.6λ op µm 10.6 10.6Detectivity*:at λ peakat λ opcmHz 1/2 /W ≥3×10 7≥1×10 7 ≥1x10 8≥5x10 7Responsivity V/W ≥0.1 ≥0.4Time Constant ns ≤0.5 ≤0.5Resistance Ω 40 to 100 40 to 100Operating temperature K 300Acceptance angle, F/# deg, - 60, 1 36, 1.62* Data sheet states minimum D* values for each detector model.
