    摘要: An arrangement adapted for a spectral analysis, having a light transmitting means, a delimited space in the form of a cavity serving as a measuring cell and defining an optical measuring distance, a light sensing means for detecting radiation passing said optical measuring distance from said light transmitting means, and a unit, connected at least to said light sensing means and performing the spectral analysis. Beams of radiation from the light transmitting means are made to pass through an optical band-pass filter at different angles of incidence. The filter is structured so as to pass a wavelength in dependence of the angle of incidence. A first chosen wavelength component is separated from a second wavelength component, each being received in its opto-electric means. Said unit is adapted for detecting and calculating an occurring radiation intensity for each such wavelength component.

    摘要: PROBLEM TO BE SOLVED: To provide a surface profile measuring device for highly accurately measuring the surface profile of an object to be measured in a simple configuration, and to provide an exposure device. SOLUTION: The surface profile measuring device makes white color light from a light source incident on a substrate and a reference face at an incident angle of 80 degrees or more by using a prism having a moth eye shaped reflection prevention part to obtain white color interference light. The device decomposes the white color interference light into interference light due to a plurality of single lights by using an optical filter enabling wavelength selection. The device performs fast Fourier transform for a plurality of the interference lights to obtain power spectrum distribution and uses peak position information of spectra to measure the surface profile of the substrate.
