MATERIALS AND METHODS FOR FLAT OPTICAL ELEMENTS

V. V. Popov

Abstract:
Consideration is given to the materials and processes suitable for the manufacturing of focusers, i.e. flat elements capable of focusing monochromatic radiation into an arbitrary line with specified intensity distribution. Methods are described for manufacturing optical elements with both surface and phase reliefs due to modulation of refractive index. Manufacturing of focusers by means of photolithography of selective etching of bichromized element, or of focusers with phase relief on layers of glass-like semiconductors are described.
