Experimental Study of Image-Forming Lens Based on Diffractive Lenses,Correcting Aberrations

Optics and Spectroscopy - The simplest lens, consisting of the refractive and diffractive lenses, in which the main geometric aberrations are compensated due to the shape of the diffractive lens,...     

Microturbines Formed with the Aid of Direct Laser Recording on Photoresist

A method for fabrication of mechanical elements (microturbines) that receive torque from vortex optical beams is proposed. Experimental results on fabrication of multiple microturbines are presented. Shapes of the microturbines are measured using an optical microscope, ZYGO white-light interferometer, and electron microscope.
