The performance of grazing incidence x-ray optical systems is severely compromised by arc-second slope errors arising from surface irregularities in the millimeter spatial period range. It is those errors that limit the performance of most of the aspheric optical systems in use at the National Synchrotron Light Source (NSLS) and it is those errors that are most difficult to control during the polishing process. We present here a set of scanning pinhole measurements made on a grazing incidence cylinder mirror which exhibit typical arc-second beam deflections and then correlate these measurements with surface roughness measurements made with a WYKO optical surface profiler. The average power spectral density (PSD) curve for the surface is computed from the profile measurements, and the various bandwidth-dependent statistical quantities, such as RMS roughness and slope error, which are computed from the PSD curve, are compared with the results from the scanning pinhole measurements.

This paper will present a brief summary of the developments in progress for chemical AR treatments of BK7 and SiO2 at Corning Glass, Schott Optical, Westinghouse and LLNL in support of the LLNL Laser Fusion Program. Details of several of these processes are tied up with patent applications or are at some point considered proprietary, but sufficient information can be revealed to show the trends of the work in progress and the potential for specific applications.

Today most lapping and figuring calculations are based on two dimensional rather than the true three dimensional geometry. This is equivalent to assuming the lens surfaces are planes rather than spheres. For most single surfaces (and this includes all figuring calculations) this is quite adequate since the deviations from reality are usually less than the noise or indeterminacy of pitch lap geometry. However, they are inadequate for deep spheres, deep lens blocks, and to answer questions of subtle cummulative effects.

Thin film interference coatings are a commonplace addition to surfaces polished in a modern optical fabrication facility. These coatings can have a dramatic effect on the optical performance of the optical component to which they are applied. In this presentation, I intend to concentrate on those effects which are related to polarization of the incident beam or the phase shift difference on reflection (retardation).

One of the crucial problems in laser fusion research is the efficient delivery of enormous amounts of power (typically several terawatts) to irradiate pellets of approximately 100 micrometer diameter. An illumination system consisting of a pair of ellipsoidal mirrors and aspheric single element lenses has been used with a two beam laser for several years at KMSF and has been very successful. 1. The lens surfaces are so steep that it is very difficult to apply anti-reflective coatings. 2. The lens must be very thick to accomodate short radii of curvature. The deleterious effects of high power beams propagating through refractive media are well known. 3. The lens also causes the system to be stigmatic for only one wavelength. The last item is especially important as recent experience has indicated that pellet energy absorption is increased by harmonically generated short wavelength and/or broadband laser light.

Most laser scanning systems for printing applications use motor-driven polygon scanners. Typically, the polygon is a polished metal part approximately 3 to 4 Inches in diameter and one-half inch thick. A common number of sides is eight to sixteen. The majority are manufactured by polishing in stacks.
