Abstract:
1. A biochip reader, comprising: a microlens plate on which a plurality of microlenses, whose outgoing angle of divergence light or collection light is limited to a narrow angle, are provided at arbitrary positions, wherein each of the plurality of the microlenses has arbitrary size; a light source which applies coherent light to the microlens plate as excitation light; a dichroic mirror which transmits or reflects outgoing light from the microlens plate, and reflects or transmits fluorescence occurring on a biochip; a photographing section; a lens which collects the light reflected or transmitted on the dichroic mirror into the photographing section; a barrier filter provided between the dichroic mirror and the photographing section; and a driving section which drives the microlens plate, wherein while the driving section drives the microlens plate, excitation light diverged or collected by the plurality of microlenses scans a surface of the biochip.
