Abstract:
The paper proposes to implement the phase function of diffractive optical elements (DOEs) in the form of a continuous relief on a flat surface. To create such a relief, the effect of mass transfer was used in the layers of liquid photopolymerizable compositions (LPPC) [1-3]. The developed technology allows to create “quasi-diffractive” optical elements (with a relief height proportional to 10-100 λ, where λ is the wavelength) that preserve the advantages of diffractive optics (minimum weight and size characteristics; unique application capabilities achieved through computer-aided microrelief design) and operate in a wide spectral range. The authors intentionally searched for the recording media that would allow to obtain an optically smooth microrelief that would not scatter light and would have a continuous profile in the range from a few microns to tens of microns. On
the basis of this effect, a technology was developed for producing laser focusing devices for a wavelength of 10.6 μm. The article presents the profilograms of the relief obtained at LPPC using mass transfer.
