Abstract: Possibilities of passive athermalization of plastic-lens systems are investigated. In particular, circuit designs of two refractive-diffractive lenses are presented, the thermal defocusing of which is eliminated by optical and mechanical methods, respectively. An achievable width of the working spectral range of the refractive-diffractive lenses is estimated.

Keywords: athermalization, thermal defocusing, achromatization, diffractive optical element, refractive-diffractive lenst.
