Title: An artifact for determining resolution of imaging based on electromagnetic radiation and/or mechanical waves
Inventor: VIITALA TAPANI
IPC: G02B21/00
Filed: 2016-05-10
Granted: 2018-06-29
Abstract: An artifact (101) for determining resolution of imaging based on electromagnetic radiation, mechanical waves, or both is presented. The artifact comprises a substrate (102) and layers (103, 104) on top of the substrate. The layers comprise organic material and are stacked on each other in a partially overlapping way so that an edge (107) of a first one of the layers is arranged to intersect with an edge (108) of a second one of the layers. The layers constitute a threedimensional surface topography where a groove (111) defined by the edges of the first and second ones of the layers is tapering towards a point of intersection (112) between the edges. The resolution is a minimum width of the tapering groove which is revealed by the imaging so that a pre-determined criterion is fulfilled.

Granted: 2023-03-01
Abstract: A manufacturing method of a master template (20) of a grating of a diffractive optic element. A layer (250) of material (200) is deposited on a substrate (108) of the master template (180) through perforations (204) of a plate (202), cross sectional areas of the perforations (204) depending on locations of the perforations (204) in the plate (202), and the plate (202) and the substrate (108) being spaced at a non-zero distance (D) from each other. Height of the at least one layer (250) on the substrate (108) is caused to vary with variation of the areas of the perforations (204). Raised formations (180) are formed on the substrate (108) by removing the at least one layer (250) from areas, which result in lowered formations (182) between the raised formations (180). A fill factor and height of the raised formations (180) are made to be proportional with each other while the raised and lowered formations (180, 182) have a relation with grooves (902) and ridges (900) of the grating (904), the relation depending on the proportionality.
