Aspherical surfaces on lenses are difficult to produce and test. There are many innovative approaches used today to address the complexities of this process. The size, quality, and quantity of the lens to be produced dictate the best approach. The UC

The primary mirror of the proposed California Extremely Large Telescope is a 30-meter diameter mosaic of hexagonal segments. An initial design calls for about a thousand segments with a hexagon side length of 0.5 meters, a primary-mirror focal ratio

DEIMOS is a large multi-object spectrograph with an imaging mode that is being built for the W. M. Keck 2 Telescope. The detector is a 2 X 4 mosaic of eight 2048 X 4096 pixel CCDs. The mosaic assembly process must position the CCDs to be planar to wi

Fabrication of the secondary mirrors for the W. M. Keck Telescopes required advances in techniques and tools for grinding, polishing, and testing. We describe the development and performance of those techniques and tools.

Instruments for large telescopes often require cameras with large, deeply-curved, and temperature-sensitive lenses. The instrument error budgets require each lens to be supported so that excellent performance is maintained in the face of gravitationa

The achieved pointing and tracking performance of the telescope is presented and compared with the Keck goals. The implications of the current performance on observing are discussed, and planned remedies for deficiencies in pointing and tracking are

Astronomical observations are now taking place on the Keck I telescope on a regular basis. We summarize here the status of the Keck I and II optics, and the current wavefront and image quality of the Keck I telescope as measured by in-telescope optic
