To counter this problem, Minsky placed a pinhole aperture at the emission side of the objective. Conjugated with the focal point of the lens (hence, "confocal"), the pinhole allowed in-focus light to ...

The key part of a confocal microscope is the pinhole placed in front of the detector at the confocal plane of the objective. Thanks to this pinhole, only light emitted from the small focal spot is ...

Confocal microscopy is an optical imaging technique that scans a focused point of light around a sample to reconstruct an image in a point-by-point manner. A pinhole is used in the detection path ...
