This Small Business Innovation Research (SBIR) Phase II project will further develop abrasive jet technology for manufacturing/finishng microoptics. Abrasion is accomplished by shear flow at the surface of the substrate submerged in an abrasive suspension and impinged upon by a bubble jet. This technology will allow the precision finishing of surfaces with an aperture size as small as 1 millimeter, and provide a scientific basis for, and demonstrate the feasibility of, new technology for optics fabrication. <br/><br/>Enabling the finishing of small, high precision molds and lenses will allow manufacture of higher resolution cameras for camera phones and other consumer products, and for medical and surveillance devices.
