Aperture: 0.40.\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThe resolution limit of the 20x\/0.40 objective is 0.69 µm.\u003c\/p\u003e\u003cp\u003eChromatic aberrations are corrected for blue and red light, spherical aberration for green light, and field curvature for 90% of the field of view diameter.\u003c\/p\u003e\u003cp\u003eThe objective is infinity-corrected. The parfocal distance is 45 mm. When observing with a 10\/22 mm eyepiece, the field of view diameter will be 1.1 mm. The objective is designed to work with samples covered with a 0.17 mm thick coverslip.\u003c\/p\u003e\u003cp\u003eThe lower limit of useful microscope magnification when observing with a 20x objective is 200x. Any magnification lower than that will not allow you to see the details of the object in the image obtained by the objective.\u003c\/p\u003e\u003cp\u003eThe upper limit of useful magnification when observing with a 20x objective is 400x. Any magnification greater than that is considered useless as it provides no new details of the sample. We recommend using eyepieces with a magnification of 10x to 20x with the 20x\/0.4 objective.\u003c\/p\u003e\u003cp\u003ePlan achromatic objectives produce an image that is uniformly in focus at both the center and edges, with minimal distortion. This feature is used for digital imaging and for pairing the objective with wide-field eyepieces and a 22 mm field of view.\u003c\/p\u003e\u003cp\u003eThe objective is suitable for studying details of the structure of a sample 1 µm or larger within a large field of view, for example, for urine analysis using the Nechiporenko method.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCompatibility:\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eMAGUS Bio 230B Biological Microscope\u003c\/li\u003e\n\u003cli\u003eMAGUS Bio 230BL Biological Microscope\u003c\/li\u003e\n\u003cli\u003eMAGUS Bio 230T Biological Microscope\u003c\/li\u003e\n\u003cli\u003eMAGUS Bio 230TL Biological Microscope\u003c\/li\u003e\n\u003cli\u003eMAGUS Bio 250B Biological Microscope\u003c\/li\u003e\n\u003cli\u003eMAGUS Bio 250BL Biological Microscope\u003c\/li\u003e\n\u003cli\u003eMAGUS Bio 250T Biological Microscope\u003c\/li\u003e\n\u003cli\u003eMAGUS Bio 250TL Biological Microscope\u003c\/li\u003e\n\u003cli\u003eMAGUS Lum 400 Fluorescence Microscope\u003c\/li\u003e\n\u003cli\u003eMAGUS Lum 400L Fluorescence Microscope\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eSpecifications:\u003c\/strong\u003e\u003cbr\u003eLens material: optical glass\u003cbr\u003eObjective class by aberration correction degree: plan achromatic\u003cbr\u003eTube length: infinity-corrected (∞)\u003cbr\u003eMagnification, x: 20\u003cbr\u003eAperture: 0.40\u003cbr\u003eWorking distance, mm: 8.8\u003cbr\u003eParfocal distance, mm: 45\u003cbr\u003eCoverslip thickness, mm: 0.17\u003cbr\u003eWith spring mechanism: -\u003cbr\u003eImmersion: -\u003cbr\u003eBody material: copper\u003cbr\u003eMount type: WJ 4\/5\"*1\/36\"\u003c\/p\u003e","brand":"MAGUS","offers":[{"title":"Default Title","offer_id":52888771985751,"sku":"82913","price":173.51,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0552\/6198\/6860\/files\/82913_magus_mp20_infinity_plan_objective_00.jpg?v=1772207510","url":"https:\/\/astrotelescopios.com\/en-efta\/products\/objetivo-magus-mp20-20%d1%85-0-40-0-17-infinity-plan","provider":"Astro Telescopios","version":"1.0","type":"link"}
