Laser application for optical glass polishing
Fidel Vega Núria Lupón Jesús Armengol Cebrian Ferran Laguarta Universitat Politècnica de Catalunya Departament d’ Òptica I Optometria C/Violinista Vellsolà 37 08222 Terrassa, Spain E-mail: [email protected] Abstract. Rapid generation of large area polished optical surfaces by high-power CO2 laser irradiation is shown. Results focus on glasses with high expansion coefficients (a>1025/°C) conventio...
متن کاملSlurry particle size evolution during the polishing of optical glass.
The particle size distribution of aqueous metal-oxide slurries can evolve during the polishing of optical glass in response to changes in mechanical and chemical process factors. The size-evolution phenomenon and its consequences were systematically studied in a planar continuous-polishing process. The concurrent application of electrokinetic techniques to characterize common optical shop mater...
متن کاملAcid polishing of lead glass
Purpose: The polishing of cut lead glass crystal is effected through the dowsing of the glass in a mixture of two separate acids, which between them etch the surface and as a result cause it to be become smooth. In order to characterise the resultant polishing the rate of surface etching must be known, but when this involves multicomponent surface reactions it becomes unclear what this rate act...
متن کاملModeling of Polishing Mechanism in Magnetic Abrasive Polishing
Magnetic Abrasive Polishing (MAP) is a super-finishing process primarily used for polishing of nonmagnetic and hard materials like, ceramics and stainless steel. This paper deals with the detailed parametric study in polishing of stainless steel work surface. Statistically designed experiments based on Taguchi methods show that size-ratio, tool-work surface clearance, polishing speed, magnetic ...
متن کاملFluid jet polishing of optical surfaces.
We present a new finishing process that is capable of locally shaping and polishing optical surfaces of complex shapes. A fluid jet system is used to guide a premixed slurry at pressures less than 6 bars to the optical surface. We used a slurry comprising water and 10% #800 SiC abrasives (21.8 mum) to reduce the surface roughness of a BK7 sample from 350 to 25 nm rms and to vary the shape of a ...
