Spatial FiltersThese pinholes and obstruction targets are used for spatial filtering of an optical beam. They are useful for creating a uniform gaussian beam, particularly in holography applications. Thorlabs offers single pinholes, annular apertures, and 16-position pinhole wheels. A motorized 16-position pinhole wheel is also available.
