摘要： An automatic focus adjusting system for a surface inspection microscope including a sheet setting stage, a microscope for observing a sheet surface set on the stage, a television camera for picking up an image observed by the microscope and a focus adjusting system. The system irradiates the back or front of an optically transparent sheet set on the stage creating an image on the front surface of the sheet. The image's contrast varies depending on the inner physical structure of the sheet. The television camera's video signals are processed by a focus evaluation circuit. The image contrast of the sheet's front surface image generates a contrast frequency allowing the focus evaluation circuit to calculate the focus evaluation degree. The system automatically adjusts the stage and compares the present focus evaluation degree with the prior focus evaluation degree. If the current focusing evaluation degree is greater than the prior focus evaluation degree the stage is adjusted one step and the process repeated until the focus evaluation circuit determines that the current focus evaluation degree is not greater than the prior focus evaluation degree.

摘要： In order to efficiently obtain data for calculating retardation values at a plurality of wavelengths, a sample having birefringence is placed between a polarizer and an analyzer, which are maintained in a parallel nicol relation to each other and rotated about an optical axis of measuring light. White measuring light is applied through the polarizer so that the light being passed through the sample and transmitted through the analyzer is received by a polychromator. A one-dimensional optical sensor is arranged on an outgoing imaging surface of the polychromator, to simultaneously detect transmitted light intensity values of a plurality of wavelengths. Since transmitted light intensity values of a plurality of wavelengths are obtained every polarization rotation angle of the polarizer and the analyzer, it is possible to obtain dispersion of retardation values with respect to wavelengths and the like by processing the data.
