The contrast is plotted in \u003cbr\u003epercentages for 5, 10, 20, 40Lp\/mm over the height of the format for tangential (dashed line) and sagittal structures (continuous line) for white \u003cbr\u003elight. The plots for 5 and 10Lp\/mm offer an impression of the contrast behavior for coarser object structures, while the 20 and 40Lp\/mm plots \u003cbr\u003edocument the resolution capability for fine and finest object structures.\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eDISTORTION\u003c\/strong\u003e\u003cbr\u003eDistortion is the deviation of the actual image height from the ideal image height, whereby the ideal image height is calculated from the object \u003cbr\u003eheight and the reproduction scale. Relative distortion states the percentage deviation of the actual to the ideal image height. The image height of \u003cbr\u003e21.6mm is the radial distance between one corner of the image field and the middle of the image field (image format 24mmx36mm). The graph \u003cbr\u003eof the effective distortion illustrates the actual line and the curvature of horizontal and vertical lines in the image horizon.\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eVIGNETTING\u003c\/strong\u003e\u003cbr\u003eVignetting is a continuous decrease of image brightness (irradiance) towards the edges of the image (shading compensation, darkening of the \u003cbr\u003eimage corners). The graph shows the diminishing brightness in percent applied over the image height.\u003cbr\u003e100% means no vignetting.","brand":"Leica","offers":[{"title":"Default Title","offer_id":46927062630575,"sku":"4022243117280","price":5500.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0734\/6415\/2239\/files\/4022243117280_0.jpg?v=1779086182","url":"https:\/\/freshized.com\/products\/leica-summilux-m-50mm-f-1-4-asph-lens-leica-m-black-2023-version","provider":"Freshized","version":"1.0","type":"link"}
