The useful magnification of a microscope with this objective is in the range of 200–400x; its maximum resolution is 0.69 µm.\u003c\/p\u003e\u003cp\u003eThe plan achromatic optics correct field curvature by 90% and produce a clear, undistorted image across almost the entire field of view. It is recommended to combine the objective with eyepieces with a wide field of view (22 mm). The combination with a 10x\/22 mm eyepiece will produce a field of view 1.1 mm in diameter. Chromatic aberration is corrected for red and blue, and spherical aberration is corrected for green.\u003c\/p\u003e\u003cp\u003eA metallurgical objective requires operation without a cover slip. The object of study may have a texture with large height differences, and with a standard objective position, there is a risk of damaging the objective or the sample. For this reason, the MAGUS 20PLL metallurgical microscope objective has a non-standard working distance of 8.8 mm.\u003c\/p\u003e\u003cp\u003eThe objective is compatible with infinity-corrected microscopes. Its parfocality is 45 mm. \u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCompatibility:\u003c\/strong\u003e\u003cbr\u003eMAGUS Metal 600 Metallurgical Microscope\u003cbr\u003eMAGUS Metal 630 Metallurgical Microscope\u003cbr\u003eMAGUS Metal 650 Metallurgical Microscope\u003cbr\u003eMAGUS Metal V700 Metallurgical Inverted Microscope\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eSpecifications\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eLens material: optical glass\u003cbr\u003eObjective class by aberration correction degree: plan achromatic\u003cbr\u003eTube length: infinity-corrected (∞)\u003cbr\u003eContrast technique: brightfield\u003cbr\u003eMagnification, x: 20\u003cbr\u003eAperture: 0.40\u003cbr\u003eWorking distance, mm: 8.80\u003cbr\u003eParfocal distance, mm: 45\u003cbr\u003eCoverslip thickness, mm: no coverslip\u003cbr\u003eSpring mechanism: −\u003cbr\u003eImmersion: −\u003cbr\u003eBody material: copper\u003c\/p\u003e","brand":"MAGUS","offers":[{"title":"Default Title","offer_id":52888790663511,"sku":"83461","price":231.36,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0552\/6198\/6860\/files\/83461_magus-20pll-plan-l-wd-objective_00.jpg?v=1772207641","url":"https:\/\/astrotelescopios.com\/en-efta\/products\/objetivo-magus-20pll-20%d1%85-0-40-plan-l-wd-8-80-mm","provider":"Astro Telescopios","version":"1.0","type":"link"}
