Abstract
Provided is a device in which light from a samplefixed in a test pieceis captured by an image sensorthrough an optical system made up of a lens, a diaphragm, and so on and concentration information is obtained, wherein a wide-band light sourcefor illuminating the test pieceis combined with an optical filterfor optionally selecting a wavelength of the light captured by the image sensor. Thus it is possible to reduce a measurement error caused by a change of the light quantity distribution of the light source
