Paper Abstract

The quality of optical surfaces generated by single-point diamond machining has been evaluated for laser printing applications. Microfinish topography of the surfaces has been analyzed by differential bidirectional laser scattering. Random and periodic surface structure, derived from the Fourier transform of the scattered-light power spectrum, are compared with interferometric surface roughness measurement. Surface tolerance may be specified for a class of laser printers by comparing the scattered intensity distribution with the analytical model of image degradation due to optical scattering. Roughness parameters have also been characterized as a function of tool radius and feed rate. Surface flatness and relative surface parameters are measured for a polygonal laser deflector. Measurement techniques are described. The characteristics of some commercially supplied micro-machined optics are discussed.
