300-mm-aperture phase-shifting Fizeau interferometer
A 300-mm-aperture digital phase-shifting Fizeau interferometer (LADI) has been developed in house for precision metrology of optical components fabricated by the Optical Workshop at CSIRO Division of… Expand
Polishing study using Teflon and pitch laps to produce flat and supersmooth surfaces.
Teflon polishing is compared with pitch polishing as a method for achieving supersmooth and flat optical surfaces. Because a Teflon lap wears slowly, it will retain its surface shape to produce… Expand
Power spectral density analysis of optical substrates for gravitational-wave interferometry.
The power spectral density of surface-relief variations on polished optical surfaces across microscopic through to macroscopic spatial scales is calculated from measurements on substrates that are… Expand
Fabrication and measurement of optics for the laser interferometer gravitational wave observatory.
The manufacture and testing of high-precision optical surfaces for the Laser Interferometer Gravitational Wave Observatory is described. Through the use of carefully shaped polishing laps made of a… Expand

The process of superpolishing with Teflon laps has enabled supersmooth [< 0.1 nm rms] and extremely flat (λ/100) optical surfaces to be produced on a large range of amorphous and crystalline optical… Expand
Electrooptic Fabry-Perot filter: development for the study of solar oscillations.
Observations of nonradial solar oscillations require Doppler velocity measurement at many points over the photosphere with a velocity resolution better than 1 m/s. An attractive form of imaging… Expand
The molar volume of silicon [Avogadro constant]
A reevaluation has been made of the density and molar mass data for the silicon single crystals used in three Avogadro projects in which the authors' institutions are cooperating. A value of 12.058… Expand
High Precision Digital Interferometry: Its Application To The Production Of An Ultrathin Solid Fabry-Perot Etalon
Teflon polishing is capable of producing surfaces flat to 3 nm or better, but its wider application requires suitable testing methods to measure such small residual errors. Digital interferometry… Expand
