Dark field microscopy is used to study unstained transparent samples. These samples absorb light weakly and are therefore not visible when viewed using the bright field microscopy technique.\u003cbr\u003e\u003cbr\u003eThe numerical aperture (N.A.) of the dark field condenser must be greater than the N.A. of the objective; therefore, the condenser works with dry objectives with a magnification power between 4x and 60x and an aperture smaller than 0.9.\u003c\/p\u003e\u003cp\u003eThe dark field condenser is installed in the microscope body to replace the Abbe condenser.\u003cbr\u003e\u003cbr\u003eTo obtain a contrast image of the sample using the dark field microscopy technique, it is recommended to use a coverslip 0.17 mm thick and a slide 1 to 1.2 mm thick.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCompatibility:\u003c\/strong\u003e\u003cbr\u003eMAGUS Bio 230B Biological Microscope\u003cbr\u003eMAGUS Bio 230BL Biological Microscope\u003cbr\u003eMAGUS Bio 230T Biological Microscope\u003cbr\u003eMAGUS Bio 230TL Biological Microscope\u003cbr\u003eMAGUS Bio 250B Biological Microscope\u003cbr\u003eMAGUS Bio 250BL Biological Microscope\u003cbr\u003eMAGUS Bio 250T Biological Microscope\u003cbr\u003eMAGUS Bio 250TL Biological Microscope\u003cbr\u003eMAGUS Lum 400 Fluorescence Microscope\u003cbr\u003eMAGUS Lum 400L Fluorescence Microscope\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eSpecifications:\u003c\/strong\u003e\u003cbr\u003eN.A.: 0.9\u003cbr\u003eImmersion medium: none\u003cbr\u003eApplicable objectives: 4x, 10x, 20x, 40x, 60x\u003c\/p\u003e","brand":"MAGUS","offers":[{"title":"Default Title","offer_id":52888774246743,"sku":"82922","price":239.63,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0552\/6198\/6860\/files\/82922_magus_df1_darkfield_condenser_00.jpg?v=1772207521","url":"https:\/\/astrotelescopios.com\/en-efta\/products\/condensador-de-campo-oscuro-magus-df1-a-0-9","provider":"Astro Telescopios","version":"1.0","type":"link"}
