The parfocal distance is 60 mm. When using a 10\/22 mm eyepiece, the field of view diameter is 1.1 mm. The objective is designed for use with samples with 0.17 mm cover slips.\u003c\/p\u003e\u003cp\u003eThe lower limit of useful microscope magnification, when using a 20x objective, is 200x. Lower magnification does not allow distinguishing details of the sample whose image is formed by the objective.\u003cbr\u003eThe upper limit of useful magnification, when using a 20x objective, is 400x. Higher magnifications are considered \"empty\" since they do not provide any new details in the image of the sample.\u003cbr\u003eWith a 20x\/0.40 objective, use eyepieces with magnifications from 10x to 20x.\u003c\/p\u003e\u003cp\u003ePlan achromatic objectives form an image that has the same focus at the center and at the edges, and therefore, distortion is negligible. This resistance is used for digital imaging and combining with wide-field eyepieces with a 22 mm field of view.\u003c\/p\u003e\u003cp\u003eThe objective is suitable for studying structural details of samples starting from 1 µm in size over a large field of view, for example, for analyzing clean catch urine samples.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCompatibility:\u003c\/strong\u003e\u003cbr\u003eMAGUS Bio 260T Biological Microscope\u003cbr\u003eMAGUS Bio DH260 Digital Biological Microscope \u003cbr\u003eMAGUS Bio 270T Biological Microscope\u003cbr\u003eMAGUS Bio 290T Biological Microscope\u003cbr\u003eMAGUS Lum 450L Fluorescence Microscope\u003c\/p\u003e\u003cp\u003e\u003cstrong style=\"mso-bidi-font-weight: normal;\"\u003e\u003cspan lang=\"ES\"\u003eSpecifications:\u003cbr\u003e\u003c\/span\u003e\u003c\/strong\u003e\u003cspan lang=\"ES\"\u003eLens material\u003c\/span\u003e\u003cspan lang=\"ES\"\u003e: \u003c\/span\u003e\u003cspan lang=\"ES\"\u003e\u003cspan lang=\"ES\"\u003eoptical glass\u003c\/span\u003e\u003c\/span\u003e\u003cspan lang=\"ES\"\u003e\u003cspan lang=\"EN-US\"\u003e\u003cbr\u003e\u003c\/span\u003e\u003c\/span\u003e\u003cspan lang=\"ES\"\u003e\u003cspan lang=\"EN-US\"\u003eObjective class by aberration correction degree: plan achromatic objective\u003cbr\u003e\u003c\/span\u003e\u003c\/span\u003e\u003cspan lang=\"ES\"\u003e\u003cspan lang=\"EN-US\"\u003eTube length: infinity (∞)\u003cbr\u003e\u003c\/span\u003e\u003c\/span\u003e\u003cspan lang=\"ES\"\u003e\u003cspan lang=\"EN-US\"\u003eMagnification, x: 20\u003cbr\u003e\u003c\/span\u003e\u003c\/span\u003e\u003cspan lang=\"ES\"\u003e\u003cspan lang=\"EN-US\"\u003eAperture: 0.40\u003cbr\u003e\u003c\/span\u003e\u003c\/span\u003e\u003cspan lang=\"ES\"\u003e\u003cspan lang=\"EN-US\"\u003eWorking distance, mm: 4.8\u003cbr\u003e\u003c\/span\u003e\u003c\/span\u003e\u003cspan lang=\"ES\"\u003e\u003cspan lang=\"EN-US\"\u003eParfocal distance, mm: 60\u003cbr\u003e\u003c\/span\u003e\u003c\/span\u003e\u003cspan lang=\"ES\"\u003e\u003cspan lang=\"EN-US\"\u003eCover slip thickness, mm: \u003cspan lang=\"ES\" style=\"font-size: 10.0pt; mso-bidi-font-size: 11.0pt; font-family: 'Arial',sans-serif; mso-fareast-font-family: Calibri; mso-fareast-theme-font: minor-latin; mso-bidi-font-family: 'Times New Roman'; mso-bidi-theme-font: minor-bidi; mso-ansi-language: ES; mso-fareast-language: EN-US; mso-bidi-language: AR-SA;\"\u003e0.17\u003c\/span\u003e\u003cbr\u003e\u003c\/span\u003e\u003c\/span\u003e\u003cspan lang=\"ES\"\u003e\u003cspan lang=\"EN-US\"\u003eSpring-loaded mount: –\u003cbr\u003e\u003c\/span\u003e\u003c\/span\u003e\u003cspan lang=\"ES\"\u003e\u003cspan lang=\"EN-US\"\u003eImmersion: –\u003c\/span\u003e\u003c\/span\u003e\u003c\/p\u003e","brand":"MAGUS","offers":[{"title":"Default Title","offer_id":52888796987735,"sku":"85066","price":318.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0552\/6198\/6860\/files\/85066_magus-20pl60-plan-20_D1_850.40-inf-h60mm-objective_00.jpg?v=1772207720","url":"https:\/\/astrotelescopios.com\/en-us\/products\/objetivo-magus-20pl60-plan-20%d1%85-0-40-0-17-h60-mm","provider":"Astro Telescopios","version":"1.0","type":"link"}
