ABSTRACT:
A confocal microscope comprising a confocal laser scanner which rotates a Nipkow disk at high speed together with microlenses wherein a beam splitter of a plate type is disposed between two integrated disks, in each of which a plurality of microlenses and minute openings are arranged with the same pattern in an array, and wherein the axis of incident light is tilted by a significant angle to the vertical incident axis of the microlenses, so that the light axis shift generated by the plate beam splitter is cancelled and the incident light to the relevant microlense is caused to be focused to the corresponding minute opening thereby improving light use efficiency.
