WebIn particular, a small circular aperture or "pinhole" that passes only the central bright spot can remove nearly all fine structure from the beam, producing a smooth transverse intensity profile, which may be almost a perfect gaussian beam. With good optics and a very small pinhole, one could even approximate a plane wave. WebMay 5, 2024 · The KT311 (/M) spatial filter system is ideal for producing a clean, spatially uniform, Gaussian beam, which is useful for many applications including holography. This spatial filter can be used to circularize an elliptical beam from a collimated laser source; see the Lab Facts tab for more details. WebApr 26, 2024 · If the pinhole diameter is below 1 AU, the lateral resolution is improved. The maximum increase in resolution is some 30% at pinhole diameter zero.
