Clear Align has introduced the Inspire line of high-performance, ultralightweight pre-engineered lenses for short-wavelength-infrared (SWIR) detection. Designed for high-resolution operation at low light levels for portable and unmanned aerial vehicle applications, the lenses’ housing design uses proprietary coatings and allows for athermalized performance in a military-ready robust package. The lenses’ f numbers range from 1.0 to 4.5. The modulation transfer function of >50% at 20 line pairs per millimeter provides high-resolution imaging for night vision, search and rescue, infrared tracking and other applications across the 0.6- to 1.7-μm imaging band. The rugged mechanical design allows the lenses to withstand hostile environments and is athermalized from —20 to 60 °C. Focal lengths range from 20 to 200 mm, and full fields of view span 48° to 1°.
