The darkfield technique is used to obtain the image of unstained translucent samples that do not absorb light well and are invisible in the bright field.\u003c\/p\u003e \u003cp\u003eThe numerical aperture of the darkfield condenser must exceed the numerical aperture of the objective. Therefore  the condenser works with dry objectives with magnifications from 4x to 40x and N.A. below 0.9.\u003c\/p\u003e \u003cp\u003eThe darkfield condenser is mounted in the arm instead of the Abbe condenser.\u003c\/p\u003e \u003cp\u003eTo obtain a contrast image of the sample using the darkfield technique  we recommend using a 0.17mm thick coverslip and a 1–1.2mm thick slide.\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eCompatibility:\u003c\/strong\u003e\u003c\/p\u003e \u003cul\u003e \u003cli\u003eMAGUS Bio 270T Biological 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\u003e5905555025513\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePackage size (LxWxH)\u003c\/td\u003e\n\u003ctd\u003e5x8x5 cm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eN.A.\u003c\/td\u003e\n\u003ctd\u003e0.7 — 0.9\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eImmersion medium\u003c\/td\u003e\n\u003ctd\u003enone\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eApplicable objectives\u003c\/td\u003e\n\u003ctd\u003e10х  20х  40х  4х\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\u003c\/table\u003e","brand":"MAGUS","offers":[{"title":"Default title","offer_id":52859756937545,"sku":"85097","price":319.95,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0426\/8032\/0154\/files\/85097_magus-df3-darkfield-condenser_00.jpg?v=1756472331","url":"https:\/\/madeiraoptics.com\/products\/magus-df3-darkfield-condenser-na-0-7-0-9","provider":"Madeira Optics","version":"1.0","type":"link"}
