We develop a theory for brightfleld and fluorescence direct‐view microscopy which allows us to determine the optical sectioning strength for finite‐sized, multiple‐pinhole arrays with an arbitrary distribution of apertures. We specialize to the …
WebJun 6, 2016 · Each pinhole may be independently filtered to yield five different spectral responses. The pinhole array is fabricated from a 1-cm thick tungsten block and is available with either straight pinholes or conical pinholes. Each pinhole within the array block is 250 μm in diameter. WebMay 1, 2024 · Pinholes work as spatial filters to ensure the circular shape and uniform spot size after the UV light is passing through. The microlenses of MLA2 then collect the UV light and project the arrayed pinhole image onto the substrate surface. Finally, an array of UV spots is formed on the substrate surface for subsequent scanning and UV exposure.
WebFeb 17, 2024 · The unique array design of this method overcomes the spatial frequency cutoff found in standard multi-pinhole arrays. In this design, the pinholes were positioned to minimize loss in spatial frequencies. The large number of pinholes results in significant overlapping on the detector. WebNov 11, 2016 · The installation of a neutron imaging diagnostic with a polar view at the National Ignition Facility (NIF) required design of a new aperture, an extended pinhole array (PHA). This PHA is different from the pinhole array for the existing equatorial system due to significant changes in the alignment and recording systems.
