3D printed hybrid refractive/diffractive achromat and apochromat for the visible wavelength range

Three-dimensional (3D) direct laser writing is a powerful technology to create nano- and microscopic optical devices. While the design freedom of this offers possibility reduce different monochromatic aberrations, reducing chromatic aberrations often neglected. In Letter, we successfully demonstrate combination refractive diffractive surfaces refractive/diffractive achromat show, best our knowledge, first apochromat by using DOEs simultaneously combining two photoresists, namely IP-S IP-n162. These combinations drastically in 3D printed micro-optics for visible wavelength range. The properties, as well substantial reduction are characterized, outline benefits written achromats apochromats micro-optics.
