ANALYSIS DEVICE AND ANALYSIS METHOD

摘要

Provided is a device in which light from a sample 7 fixed in a test piece 1 is captured by an image sensor 5 through an optical system made up of a lens 3, a diaphragm 4, and so on and concentration information is obtained, wherein a wide-band light source 12 for illuminating the test piece 1 is combined with an optical filter 13 for 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 12.
