Bases: OpticalAperture_Type
Represents the XML element Pinhole.
A pin-like aperture positioned axially to the Light Path, which can act as a spatial filter for a beam of light to clean up the output of lasers and / or to suppress out-of-focus light in a confocal Microscope. Specifically, in Confocal Microscopy, such Pinholes are diaphragm typically situated in a plane conjugate with the object, and they restrict the area in the object plane that is illuminated and/or from which light is collected.
