Magnification: 40x. Aperture: 0.60\u003cbr\u003e\u003cbr\u003eThe phase objective is used to study living biological samples that are indistinguishable using the brightfield method. Due to staining, microorganisms die, so the phase contrast method is the only one that allows examining biological samples without contrast. In addition to the objective, for it to work, you will need a phase condenser with a 40x annular diaphragm or a phase contrast annular plate with a ring for the corresponding objective magnification.\u003c\/p\u003e\u003cp\u003eThe objective is designed for installation on an inverted biological or fluorescence microscope and will fit into an infinity-corrected optical system. The parfocal distance is 45mm. Biological samples are studied on labware with a bottom thickness of 1.2mm.\u003c\/p\u003e\u003cp\u003eIt is compatible with eyepieces with magnifications from 7.5x to 15x: in such a system, the useful magnification of the microscope will be from 300x to 600x. A lower eyepiece magnification will not provide a detailed image; a magnification above the 15x threshold will not be effective, as it will not provide any new information.\u003c\/p\u003e\u003cp\u003eThe objective corrects optical distortions: chromatic in red and blue, spherical in green. Distortion occupies 10% of the visible field. The large flat field works well when working with a digital camera or in a system with a 22mm eyepiece. A 10x\/22mm eyepiece will provide a field of view of 0.55mm.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCompatibility:\u003cbr\u003e\u003c\/strong\u003eMAGUS Bio V300 Inverted Biological Microscope\u003cbr\u003eMAGUS Bio V350 Inverted Biological Microscope\u003cbr\u003eMAGUS Lum V500 Inverted Fluorescence Microscope\u003cbr\u003eMAGUS Lum V500L Inverted Fluorescence Microscope\u003c\/p\u003e\u003cp\u003e\u003cspan lang=\"ES\"\u003e\u003cstrong\u003eSpecifications\u003c\/strong\u003e\u003cbr\u003e\u003c\/span\u003e\u003cspan lang=\"ES\"\u003eLens material: optical glass\u003cbr\u003e\u003c\/span\u003eObjective class by aberration correction degree: Plan achromatic\u003cbr\u003eTube length: infinity corrected (∞)\u003cbr\u003eContrast technique: phase contrast\u003cbr\u003eMagnification, x: 40\u003cbr\u003eAperture: 0.60\u003cbr\u003eWorking distance, mm: 3.5\u003cbr\u003eParfocal distance, mm: 45\u003cbr\u003eBottom thickness, mm: 1.2\u003cbr\u003eSpring mechanism: +\u003cbr\u003eImmersion: −\u003cbr\u003eBody material: copper\u003c\/p\u003e","brand":"MAGUS","offers":[{"title":"Default Title","offer_id":52888788566359,"sku":"83439","price":327.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0552\/6198\/6860\/files\/83439_magus-40hp-40x-plan-l-php2-objective_00.jpg?v=1772207619","url":"https:\/\/astrotelescopios.com\/en-uk\/products\/objetivo-magus-40hp-40%d1%85-0-60-plan-l-fase-php2-1-2-wd-3-5-mm","provider":"Astro Telescopios","version":"1.0","type":"link"}
