ABSTRACT:
A microchip testing device with a microchip having an absorbance measuring chamber for measuring absorbance, a transmitted light receiving unit for receiving light which has been emitted from a light source and has been transmitted through the absorbance measuring chamber, an aperture which extends in a straight line in the direction of the optical axis of the absorbance measuring chamber, with an entry opening for the light emitted by the light source on one end and a light exit opening on an opposite end from which the light enters the absorbance measuring chamber, an incident light beam splitter which is located in the optical path between the light exit opening of the aperture and the absorbance measuring chamber and which transmits part of the incident light and reflects another part of it, and a reflected light receiving part for receiving the light which has been reflected by the beam splitter.
