摘要： A focusing screen for observing an image formed by an objective lens is constructed of a liquid crystal layer, having a dynamic scattering effect, sandwiched between a pair of parallel transparent electrodes. At least one of the transparent electrodes is divided into a plurality of discrete parts. The discrete electrode parts are connected as independent groups through a switch mechanism to a driving circuit. The switch mechanism permits one or more of the groups to act as different elements in response to an applied voltage, depending on the F value of the lens. Accordingly, the scattering degree of the focusing screen varies as a function of the F value and not the applied voltage.

摘要： The preparation apparatus 4 determines the target distribution of the amount of polishing on the basis of the film thickness of the wafer 2 measured by the measuring apparatus 3. The preparation apparatus 4 assumes a control program for the purpose of controlling the polishing apparatus 1, and predicts the distribution of the amount of polishing that is obtained after the wafer 2 is polished by the polishing apparatus 1 in accordance with the assumed control program. In this case, the amount of polishing in individual partial regions of the polished surface of the wafer 2 is predicted using an indicator that indicates the height distribution of the polishing surface of the polishing pad 14 (when no pressure is applied to this polishing pad) as one parameter. The preparation apparatus 4 judges the acceptability of the assumed control program by comparing the predicted distribution of the amount of polishing and the target distribution of the amount of polishing. The polishing apparatus 1 polishes the wafer 2 in accordance with a control program that has been judged to be acceptable. As a result, the desired film thickness distribution on the side of the polished surface of the object of polishing can be simulated with good precision.

摘要： A liquid crystal element includes a liquid crystal having a molecular orientation varying according to an applied voltage, first upper and lower electrodes which are opposed in plane to each other and between which the liquid crystal is interposed, and second upper and lower electrodes which are not opposed in plane to each other and between which the liquid crystal is interposed.

A pair of transparent electrodes apply the electric field to the liquid crystal layer. At least one of the transparent electrodes is provided with a great number of holes distributed at random over its entire surface, whereby the optical performance and particularly the MTF value of the light passing through the liquid crystal layer due to the double-refracting property of the liquid crystal layer is made variable.
