METHOD OF FORMATION OF LIQUID OPTICAL SURFACES Russian patent published in 1998 - IPC

FIELD: optical engineering. SUBSTANCE: optical surfaces are formed when pouring several nonmixing or partially mixing liquids with use of carbon tetrafluoride liquids as one components with common formula C_nF_m, which makes it possible to use relief surfaces obtained as mechanically unimpaired passive and active optical elements (lenses, transparent and colored diaphragms, laser elements and decorative forms). When nonequilibrium pressure of vapors C_nF_m is created in dishes constant motions and oscillations arise in liquids, which allows formation of unstable optical elements. EFFECT: high-quality optical surfaces. 2 cl
