Granados Agustin Física, Astronomía y Matemáticas Diffraction and scattering optical instruments and equipment An analysis of different structures of the spiders supporting the flat mirror of a Newton type telescope was made, in order to reduce thediffraction effects of the spider on the images produced by the telescope. After applying different numerical solutions used by differentauthors, and without satisfactory results, a novel solution based on the analysis of the diffraction pattern of a circular aperture allowed usto find a satisfactory reduction of the diffraction pattern in the image produced by the support of the secondary flat mirror. Experimentallaboratory results will be shown, using white and He-Ne laser light sources. 2005 artículo científico 0035-001X https://www.redalyc.org/articulo.oa?id=57063716 en http://www.redalyc.org/revista.oa?id=570 Revista Mexicana de Física application/pdf Sociedad Mexicana de Física A.C.
