Since that most materials have properties that change with temperature, and all the materials that can be used to make lens for the LWIR waveband have properties that change.
By adopting the optical or mechanical compensation in the lenses design, the athermalized infrared lenses are insensitive to environmental temperature variations and maintain the focus position without power.
