LASER MICROSCOPE APPARATUS

摘要

By using a PPD as a detector, photon count loss is reduced to the utmost, and the incident light-intensity range in which light can be detected is widened. Provided is a laser microscope apparatus including an objective lens that collects return light from a specimen; a collimator lens that converts the return light collected by the objective lens into a substantially collimated beam, a PPD including a plurality of pixels that detect the return light converted to a substantially collimated beam by the collimator lens; and a controller that makes the beam diameter of the return light incident on the PPD substantially equal to an effective detection area of the PPD, formed by the plurality of pixels.

1. A laser microscope apparatus comprising:
an objective lens that collects light from a specimen; a photodetector including a plurality of detection elements that detect the light collected by the objective lens; and an adjusting mechanism that makes a beam diameter of the light incident on the photodetector substantially equal to an effective detection area of the photodetector formed by the plurality of detection elements.
