LWIR 20mm F/1.2 fixed-focal lenses

To accommodate the needs of the market in transition, Tamron 's new LWIR 20mm F/1.2 fixed-focal lenses (Models: LQF2012N / LQF2012A) are compatible with the industry-leading 10-12μm pixel-pitch detectors. By use of a proprietary optical design, the effective image circle is expanded to support the widely-used 17 μm pixel-pitch QVGA format while attaining a compact and lightweight barrel construction. As the package size of the LWIR detectors associated with pixel pitch miniaturization becomes smaller, overall sensitivity tends to suffer due to inherent pixel opening dimensions. To compensate for deficits in sensitivity, the new lenses are designed with F/1.2.
