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...

Slurry 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...

Acid 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...

Laser Assisted Chemical Mechanical Polishing for Planarization

11.3 Polishing with Laser Radiation

The surface roughness of a part or product strongly influences its properties and functions. Among these can be counted abrasion and corrosion resistance, tribological properties, optical properties, haptics as well as the visual impression the customer desires. Therefore, in industrial manufacturing grinding and polishing techniques are widely used to reduce the roughness of surfaces. A new me...
