Chromatic aberrations are corrected for blue and red  spherical aberration for green  and the field curvature is corrected for 90% of the field of view diameter.\u003c\/p\u003e \u003cp\u003eThe objective is designed for the infinity-corrected tube length. The parfocal distance is 60mm. When a 10\/22mm eyepiece is used  the diameter of the field of view is 1.1mm. The objective is designed to be used with specimens with 0.17mm coverslips.\u003c\/p\u003e \u003cp\u003eThe lower limit of the microscope’s useful magnification  when a 20x objective is used  is 200x. Lower magnification does not allow you to distinguish the details of the specimen whose image is formed by the objective. The upper limit of the useful magnification  when a 20x objective is used  is 400x. Higher magnification is considered “useless” as it provides no new detail in the image of the sample. With the 20x\/0.40 objective  use the eyepieces with magnifications from 10x to 20x.\u003c\/p\u003e \u003cp\u003ePlan achromatic objectives form an image that has the same focus in the center and at the edges and  therefore  the distortion is negligible. This strength is used for digital imaging and combining them with wide-field eyepieces with a 22mm field of view.\u003c\/p\u003e \u003cp\u003eThe objective is suitable for studying the structural details of the specimens from 1µm in size in a large field of view  e.g.  for analyzing clean catch urine samples.\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eCompatibility:\u003c\/strong\u003e\u003c\/p\u003e \u003cul\u003e \u003cli\u003eMAGUS Bio 260T Biological Microscope\u003c\/li\u003e \u003cli\u003eMAGUS Bio DH260 Biological Digital Microscope\u003c\/li\u003e \u003cli\u003eMAGUS Bio 270T Biological Microscope\u003c\/li\u003e \u003cli\u003eMAGUS Bio 290T Biological Microscope\u003c\/li\u003e \u003cli\u003eMAGUS Lum 450L Fluorescence Microscope\u003c\/li\u003e \u003c\/ul\u003e\u003ctable\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eMAGUS\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWarranty\u003c\/td\u003e\n\u003ctd\u003e2 years\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eEAN\u003c\/td\u003e\n\u003ctd\u003e5905555025209\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePackage size (LxWxH)\u003c\/td\u003e\n\u003ctd\u003e3x5x3 cm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLens material\u003c\/td\u003e\n\u003ctd\u003eoptical glass\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eObjective class by aberration correction degree\u003c\/td\u003e\n\u003ctd\u003eplan achromatic\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMagnification  x\u003c\/td\u003e\n\u003ctd\u003e20\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAperture\u003c\/td\u003e\n\u003ctd\u003e0.4\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWorking distance  mm\u003c\/td\u003e\n\u003ctd\u003e4.8\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eParfocal distance  mm\u003c\/td\u003e\n\u003ctd\u003e60\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCover glass thickness  mm\u003c\/td\u003e\n\u003ctd\u003e0.17\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCompatible tube length  mm\u003c\/td\u003e\n\u003ctd\u003einfinity\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSpring-loaded frame\u003c\/td\u003e\n\u003ctd\u003eno\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eImmersion\u003c\/td\u003e\n\u003ctd\u003eno\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\u003c\/table\u003e","brand":"MAGUS","offers":[{"title":"Default title","offer_id":52669852025161,"sku":"85066","price":269.95,"currency_code":"EUR","in_stock":true}],"url":"https:\/\/madeiraoptics.com\/products\/magus-20pl60-plan-20h-0-40-0-17-h60mm-objective","provider":"Madeira Optics","version":"1.0","type":"link"}
