Holographic lenses stored in Biophotopol

Innovative technologies demand versatile and environmentally compatible optical elements. In this paper we evaluated the quality of volume phase transmission lenses stored in a biocompatible photopolymer. Holographic lenses (HL) have been obtained with the same focal and diameter, for a symmetric and asymmetric experimental setups, and positive and negative focal. The quality of these lenses have been evaluated: theoretically and experimentally, from the calculation of the modulation transfer function (MTF) by capturing the point spread function (PSF) with a CCD sensor. The HLs that have shown better quality are the negative asymmetrically recorded compared with the theoretical ones.
