Abstract

Basing on the experimental measurements of the birefringence of a set of liquid crystals, possible approaches of designing achromatic optical phase retarders are discussed. It is shown that while theoretically precision of achievable achromatism is unlimited, in practice it is not better that 10 percent. Angular parameters of such retarders and methods of their improvement are analyzed in details.
