Abstract:
1. An absorbance reading apparatus for reading the absorbance of a sample injected into each of a plurality of wells provided on a microchamber array, the apparatus comprising: a sample base for mounting the microchamber array; a light source; a spectroscope on which light from the light source is incident; an irradiation optical system for adjusting the distribution of luminance of irradiation light emerging from the spectroscope; a field lens for enlarging the size of irradiation light transmitted by the irradiation optical system and irradiating the microchamber array mounted on the sample base with the enlarged irradiation light; a one-side telecentric optical system for receiving sample-transmitted light; and an imaging camera for producing image data based on the sample-transmitted light received via the one-side telecentric optical system.
