PROCESS FOR CLEANING PRECISION OPTICS OR OPTICAL ASSEMBLIES WITHOUT PRODUCING EMISSIONS, ESPECIALLY CFCs

摘要

a cleaning process without emissions of precision optical elements comprises the following steps: (a) a pre processing, which includes cleaning a bath with the tap water, buffered plus surfactants as wetting agent, the bath... ant released and finely filtering, cleaning is accompanied by exposure to ultrasound.preferably with variable frequencies and amplitudes. the optical elements are then rinsed with tap water and buffered without wetting agents, exposure to ultrasound, so that fresh water is finely filtered; a cleaning and rinsing a new you s, as well as a rincage buffered with deionized water.with exposure to ultrasound and agitation with the deionized water, at the same time, the bath is finely filtered; (b) the decomposition of organic impurities and remnants of surfactants to transform them into co2 by exposure to short wave uv radiation, or highly accelerated electrons or a glow discharge.in an atmosphere of oxygen without pressure or under a pressure of up to 5 bar, or in an atmosphere of ozone without pressure or under a pressure of up to 2 bars; (c) control of the interfaces of the glass optical elements which is feedback with organic radicals.decomposition reaction on the surface of the glass or changes in the geometry of the surface; and (d) a primary treatment, consisting of the following steps: removal of the water at the surface of the glass.for example, by means of reactive hydrophobic, hydrophobic substances, not volatile or non-volatile, sealing of the surface by the formation of a film by exposure to uv or electronic and surface coating, so that the sealing surface is a layer of into a metal oxide by glow discharge and is activated by glow discharge.the optical component is cleaned according to the
