AUTO FOCUSING APPARATUS FOR AN OPTICAL MICROSCOPE ADDING AN OPTICAL RECEIVER HAVING A CONFOCAL TYPE

摘要

PURPOSE: An auto focusing apparatus for an optical microscope is provided to automatically adjust the focus of the optical microscope using a laser scanning mode.;CONSTITUTION: An auto focusing apparatus for an optical microscope using a laser scanning mode includes a focus detection unit(210), a space filter unit and a control unit. The focus detection unit includes a light emitter(212), a wedge mirror(218), a first light receiver(226) and a second light receiver(228). The light emitter emits light having a specific wavelength. The wedge mirror capable of rotating projects the emitted light to multiple spots on the surface of a sample. The first receiver and the second receiver detect the light quantity of laser light reflected at the surface of the sample. In the light reflected at the surface of the sample, a space filter unit removes light which is out of focus and detects the light quantity of light which is in focus. The control unit generates a control signal for performing the focus adjustment of the optical microscope using light quantity information detected through the first receiver, the second receiver and the space filter unit.;COPYRIGHT KIPO 2013;[Reference numerals] (130) Camera
