Abstract:
The present invention provides a measurement apparatus including a first filter unit including a plurality of first filters, and each configured to allow light having a different wavelength band to pass, a second filter unit including a plurality of second filters, and each configured to reduce light intensity of light and allow the light to pass, an obtaining unit configured to obtain data representing a transmittance of each of the plurality of second filters for a wavelength band of light having passed through each of the plurality of first filters, and a selection unit configured to select, based on the data obtained by the obtaining unit, from the plurality of second filters, one second filter arranged on an optical path together with one first filter among the plurality of first filters.

Claim (Index 18):
A method of manufacturing an article, comprising:\n exposing a substrate using an exposure apparatus, developing the exposed substrate; and manufacturing the article from the developed substrate, wherein the exposure apparatus includes a projection optical system configured to project a pattern of a reticle onto the substrate, a stage configured to hold the substrate, a measurement apparatus configured to measure a position of the substrate by detecting a mark on the substrate, and a control unit configured to control a position of the stage based on a measurement result of the measurement apparatus, and the measurement apparatus includes a filter unit including a plurality of second filters arranged on an optical path between a light source configured to output light for illuminating the mark and an image sensor configured to capture the mark, each of the plurality of second filters being configured to reduce light intensity of light and allow the light to pass, and a selection unit configured to obtain data representing a transmittance of each of the plurality of second filters for a wavelength band of light to be used for illuminating the mark, and select, based on the data, from the plurality of second filters, one second filter to be used for light control of the light for illuminating the mark.
