[[abstract]]This study demonstrated a color-filter Fresnel lens in polymer-stabilized cholesteric liquid crystals (PSCLCs). The liquid crystals in the odd zones were in a planar cholesteric texture, the Bragg reflection band of which was located in the infrared region. The even zones had a focal conic texture. The linearly polarized white light passing through the planar texture underwent optical activity. The light with the polarization perpendicular to the transmission axis of an analyzer behind the PSCLC Fresnel lens was eliminated. Changing the orientation of the transmission axis of the analyzer can select the color of the focusing image
