Abstract
A conveyance device supports and conveys an object. The conveyance device has a support portion in which an opening narrower than the object is provided at a position where the object is supported. A lighting device irradiates a first surface of the object with measurement light having a wavelength changing over time through the opening of the support portion. A light receiving device detects object light that is diffusely transmitted light emitted from a second surface of the object.
