The darkfield technique is used to image translucent unstained samples that do not absorb light well and are invisible in brightfield.\u003c\/p\u003e\u003cp\u003eThe numerical aperture of the darkfield condenser should exceed the numerical aperture of the objective. Therefore, the condenser works with dry objectives with magnifications from 4x to 40x and N.A. less than 0.9.\u003c\/p\u003e\u003cp\u003eThe darkfield condenser is installed in the microscope body to replace the Abbe condenser.\u003c\/p\u003e\u003cp\u003eTo obtain a contrast image of the sample using the darkfield technique, it is recommended to use a coverslip 0.17 mm thick and a slide 1–1.2 mm thick.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCompatibility:\u003c\/strong\u003e\u003cbr\u003eMAGUS Bio 270T Biological Microscope\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eSpecifications:\u003c\/strong\u003e\u003cbr\u003eNumerical aperture: 0.7–0.9\u003cbr\u003eImmersion medium: dry\u003cbr\u003eApplicable objectives: 4х, 10х, 20х, 40х\u003c\/p\u003e","brand":"MAGUS","offers":[{"title":"Default Title","offer_id":52888799084887,"sku":"85097","price":319.95,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0552\/6198\/6860\/files\/85097_magus-df3-darkfield-condenser_00.jpg?v=1772207737","url":"https:\/\/astrotelescopios.com\/en-eu\/products\/condensador-de-campo-oscuro-magus-df3-n%d0%b0-0-7-0-9","provider":"Astro Telescopios","version":"1.0","type":"link"}
