SupIR 19-275 mm f/5.5 Motorized MWIR Zoom Imaging Lens

MWIR Continuous Zoom Lens, SupIR, 19-275 mm FL, f/5.5, Hard Carbon

The SupIR 19-275mm f/5.5 motorized focus MWIR imaging lens (P/N 6519634) has a 19-275 mm focal length with an f-number of 5.5. This continuous zoom lens features our hard carbon antireflection coating and is designed for standard definition format cooled MWIR cameras. These lenses provide a crisp image over the full zoom range, with MTF close to the diffraction limit. Providing outstanding detection, recognition and identification (DRI) ranges, these MWIR lenses are suitable for a wide range of commercial, surveillance and homeland security applications.
