Techniques designed for assessing the performance of lenses operating in the 8-13 micron band are described. These include interferometry and pupil scanning, both using monochromatic radiation from a CO2 laser source. In addition a nominally polychromatic line spread function apparatus is shown. Results are presented of MTF using these techniques, along with those from a commercially available polychromatic grating scanning instrument. Measurements have been made on standard audit and operational lenses. Comparisons are made and differences attributable to radiation source emphasised.
