摘要：

The diffraction-based performance limitations of dual waveband infrared systems which incorporate hybrid refractive-diffractive lenses are examined. These limitations must be understood in order to identify the key trade-offs and optimise the design of the diffractive element. The correction of chromatic aberration is considered and the range of conditions under which hybrid solutions offer an advantage is established. A dual waveband hybrid objective lens for an uncooled staring array camera has been designed, manufactured and evaluated.
