Abstract

For the dual waveband detector of the TICM II thermal imaging system which is sensitive over the wavelength range from 3gm to 5gm and from 8gm to 12gm an afocal with magnification change has been designed. The afocal is color corrected for both wavelength bands without focus shift and it has a reduced Petzval-sum.
