The objectives are placed in the revolving nosepiece instead of standard objectives  and the MAGUS BD90 darkfield module is installed in the turret of the reflected light illuminator.\u003c\/p\u003e \u003cp\u003eThe objectives are designed for both brightfield and darkfield observations. When a sample is illuminated by light through the objective  there are no shadow areas. Therefore  it is difficult to assess the surface topography using the brightfield technique. When the MAGUS BD90 darkfield module and a darkfield objective are introduced into the optical path  the sample is illuminated from the side by oblique light. This creates shadows at the grain boundaries  revealing the surface relief.\u003c\/p\u003e \u003cp\u003eThe objectives in the set are infinity plan semi-apochromatic and infinity plan apochromatic  which provide a higher degree of correction for chromatic and spherical aberrations than plan achromatic objectives. The image seen through the eyepieces and digital camera is cleaner and has greater contrast and brightness. Five objectives with magnifications of 5х  10х  20х  50х  and 100х are included in the set. The parfocal distance is 60mm.\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eCompatibility:\u003c\/strong\u003e\u003c\/p\u003e \u003cul\u003e \u003cli\u003eMAGUS Pol 890 Polarizing Microscope\u003c\/li\u003e \u003c\/ul\u003e \u003cp\u003e\u003cstrong\u003ePackage:\u003c\/strong\u003e\u003c\/p\u003e \u003cul\u003e \u003cli\u003eInfinity plan semi-apochromatic objective: 5х\/0.15 BD  parfocal distance: 60mm\u003c\/li\u003e \u003cli\u003eInfinity plan semi-apochromatic objective: 10х\/0.30 BD  parfocal distance: 60mm\u003c\/li\u003e \u003cli\u003eInfinity plan semi-apochromatic objective: 20х\/0.45 BD  parfocal distance: 60mm\u003c\/li\u003e \u003cli\u003eInfinity plan apochromatic objective: 50х\/0.80 BD  parfocal distance: 60mm\u003c\/li\u003e \u003cli\u003eInfinity plan apochromatic objective: 100х\/0.90 BD  parfocal distance: 60mm\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\u003e5905555026220\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\u003c\/table\u003e","brand":"MAGUS","offers":[{"title":"Default title","offer_id":52789553398089,"sku":"85159","price":6239.95,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0426\/8032\/0154\/files\/85159_magus-s-apo-bd60-plan-s-apo-objective-set_00.jpg?v=1755024738","url":"https:\/\/madeiraoptics.com\/en\/products\/magus-s-apo-bd60-plan-s-apo-5h-10h-20h-50h-100h-bd-h60mm-objective-set-for-bright-dark-field-observa","provider":"Madeira Optics","version":"1.0","type":"link"}
