Using principles of light-diffraction to suppress field-illumination, the condenser illuminates edges of cells, microorganisms, and other objects. This is particularly useful for live blood analysis.\u003c\/p\u003e\n\n\u003cp\u003eThis darkfield condenser is designed for use with immersion oil. The 1.36 maximum numerical aperture will accommodate higher-magnification objective lenses with numerical apertures up to 1.25. However, it is recommended to use objective lenses with numerical apertures at or below 1.0 for true darkfield. Objective lenses designed for darkfield, such as those with iris-control like our PA100X-IRIS, are recommended for high magnifications. As well, magnifications of 10X and below may experience vignetting, in which case a dry condenser is preferable.\u003c\/p\u003e\n\n\u003cp\u003eThis condenser is designed to work with compound microscopes with a 37mm front-mount condenser holder. Compatible models include: T670, T670Q-PL, T750, FM820T\u003c\/p\u003e\n\n\u003cdiv style=\"max-width:600px; text-align:left;\"\u003e\n\u003ctable style=\"width:100%;\"\u003e\n\t\u003ctr\u003e\u003ctd colspan=\"2\" style=\"font-size:2em; text-align:left;\"\u003eCondenser Compatibility\u003c\/td\u003e\u003c\/tr\u003e\n    \u003ctr\u003e\u003ctd colspan=\"2\" style=\"border-top:#808080 1px solid;\"\u003e\u003c\/td\u003e\u003c\/tr\u003e\n\t\u003ctr\u003e\n    \t\u003ctd style=\"vertical-align:top; padding:.05em;\"\u003eCondenser Mount\u003c\/td\u003e\n        \u003ctd style=\"vertical-align:top; padding:.05em 0; padding-left:1em;\"\u003efront mount\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\u003ctd colspan=\"2\" style=\"border-top:#808080 1px solid;\"\u003e\u003c\/td\u003e\u003c\/tr\u003e\n    \u003ctr\u003e\n    \t\u003ctd style=\"vertical-align:top; padding:.05em;\"\u003eMounting Diameter\u003c\/td\u003e\n        \u003ctd style=\"vertical-align:top; padding:.05em 0; padding-left:1em;\"\u003e37mm\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\u003ctd colspan=\"2\" style=\"border-top:#808080 1px solid;\"\u003e\u003c\/td\u003e\u003c\/tr\u003e\n    \u003ctr\u003e\n    \t\u003ctd style=\"vertical-align:top; padding:.05em;\"\u003eModel Compatibility\u003c\/td\u003e\n        \u003ctd style=\"vertical-align:top; padding:.05em 0; padding-left:1em;\"\u003eT670, T670Q-PL, T750, FM820T\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\u003ctd colspan=\"2\" style=\"border-top:#808080 1px solid;\"\u003e\u003c\/td\u003e\u003c\/tr\u003e\n    \n    \u003ctr\u003e\u003ctd colspan=\"2\" style=\"font-size:2em; text-align:left;\"\u003eCondenser Specifications\u003c\/td\u003e\u003c\/tr\u003e\n    \u003ctr\u003e\u003ctd colspan=\"2\" style=\"border-top:#808080 1px solid;\"\u003e\u003c\/td\u003e\u003c\/tr\u003e\n    \u003ctr\u003e\n    \t\u003ctd style=\"vertical-align:top; padding:.05em;\"\u003eNumerical Aperture\u003c\/td\u003e\n        \u003ctd style=\"vertical-align:top; padding:.05em 0; padding-left:1em;\"\u003e1.25-1.36\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\u003ctd colspan=\"2\" style=\"border-top:#808080 1px solid;\"\u003e\u003c\/td\u003e\u003c\/tr\u003e\n    \u003ctr\u003e\n    \t\u003ctd style=\"vertical-align:top; padding:.05em;\"\u003eImmersion Medium\u003c\/td\u003e\n        \u003ctd style=\"vertical-align:top; padding:.05em 0; padding-left:1em;\"\u003eoil\u003c\/td\u003e\n    \u003c\/tr\u003e\n\u003c\/table\u003e\n\u003c\/div\u003e","brand":"AmScope","offers":[{"title":"Default Title","offer_id":56836420403580,"sku":"DK-OIL-670","price":128.99,"currency_code":"GBP","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0556\/1974\/7905\/files\/oil-darkfield-condenser-dk-oil-670-01.jpg?v=1780521684","url":"https:\/\/amscope.co.uk\/products\/amscope-dk-oil-670-oil-immersion-darkfield-condenser-for-compound-microscope-with-na-1-25-to-1-36-and-670-class","provider":"AmScope UK","version":"1.0","type":"link"}
