The technique improves resolution and image clarity by optical rather than chemical means, and provides additional information about the sample structure. \u003cbr\u003e\u003c\/span\u003e\u003cspan lang=\"ES\"\u003eThe DIC technique introduces a pseudo-relief imaging effect. The color and intensity effects in the image are determined by the rate of change of the refractive index and the thickness of adjacent sections of the sample. The image of the sample appears three-dimensional. The three-dimensional view does not show the actual geometry of the sample, but rather colors it based on optical thickness. This technique is not suitable for measuring actual height and depth.\u003cbr\u003e\u003c\/span\u003e\u003cspan lang=\"ES\"\u003eThe DIC and phase contrast techniques complement each other. They produce similar contrast images, but DIC images do not have diffraction phase contrast halos around samples. These halos are the result of the difference between the refractive index of the sample and the surrounding medium. They often obscure details at the edges of the observed structures. The DIC technique allows these details to be seen.\u003c\/span\u003e\u003c\/p\u003e\u003cp class=\"MsoNormalCxSpFirst\"\u003e\u003cspan lang=\"ES\"\u003eThe differential interference contrast device includes a DIC condenser, a polarizing filter, and DIC slider compensators.\u003c\/span\u003e\u003c\/p\u003e\u003cp class=\"MsoNormalCxSpFirst\"\u003e\u003cstrong style=\"mso-bidi-font-weight: normal;\"\u003e\u003cspan lang=\"ES\"\u003eDIC condenser\u003c\/span\u003e\u003c\/strong\u003e\u003c\/p\u003e\u003cp class=\"MsoNormalCxSpFirst\"\u003e\u003cspan lang=\"ES\"\u003eThe DIC condenser is installed as a replacement for the brightfield condenser. The turret includes DIC prisms and a slot that is used during brightfield observations. The DIC prisms in the turret are used depending on the objective used. Below the turret is an aperture diaphragm adjustment control that is used when working in brightfield.\u003c\/span\u003e\u003c\/p\u003e\u003cp class=\"MsoNormalCxSpFirst\"\u003e\u003cstrong style=\"mso-bidi-font-weight: normal;\"\u003e\u003cspan lang=\"ES\"\u003eDIC slider compensators\u003c\/span\u003e\u003c\/strong\u003e\u003c\/p\u003e\u003cp class=\"MsoNormalCxSpFirst\"\u003e\u003cspan lang=\"ES\"\u003eThe DIC slider compensator is installed in a special slot in the revolving nosepiece. The DIC slider compensator is used in combination with the corresponding objective. The slider compensator is a plate with a DIC prism and an analyzer. The MAGUS DIC290 device includes two slider compensators: one is used with 10x and 20x objectives, and the other with 40x and 100x objectives. Rotating the slider knob moves the DIC prism in the transverse direction.\u003c\/span\u003e\u003c\/p\u003e\u003cp class=\"MsoNormalCxSpFirst\"\u003e\u003cstrong style=\"mso-bidi-font-weight: normal;\"\u003e\u003cspan lang=\"ES\"\u003ePolarizing filter\u003c\/span\u003e\u003c\/strong\u003e\u003c\/p\u003e\u003cp class=\"MsoNormalCxSpFirst\"\u003eWhen using the DIC technique, light from the illuminator is passed through a polarizing filter. The polarizer is placed in the collector and secured with a knurled head screw. The polarizer is marked with a rotation angle scale and can be rotated 360°. The intensity of the transmitted light varies depending on the position of the polarizer and analyzer. When they are mutually perpendicular to each other, a complete darkening effect is observed. The polarizer can also be swung down: it is not necessary to remove it from the microscope to take it out of the optical path.\u003c\/p\u003e\u003cp class=\"MsoNormalCxSpFirst\"\u003e\u003cstrong style=\"mso-bidi-font-weight: normal;\"\u003e\u003cspan lang=\"ES\"\u003eRecommended objectives\u003c\/span\u003e\u003c\/strong\u003e\u003c\/p\u003e\u003cp class=\"MsoNormalCxSpFirst\"\u003e\u003cspan lang=\"ES\"\u003eObjectives are not included in the MAGUS DIC290 device kit.\u003cbr\u003e\u003c\/span\u003e\u003cspan lang=\"ES\"\u003eThe DIC technique requires precise positioning of the optical components relative to each other: the lower DIC prism, relative to the front focal plane of the condenser, and the upper DIC prism, relative to the back focal plane of the objective. The MAGUS DIC290 device is designed for the MAGUS Bio 290T microscope and, therefore, it is recommended to use the objectives supplied with or compatible with the microscope for DIC observations.\u003cbr\u003e\u003c\/span\u003e\u003cspan lang=\"ES\"\u003eWe recommend using MAGUS FL S-APO60 PlanF objectives with a larger aperture. A larger aperture of an objective allows focusing a thin flat section of a thick sample, which is called optical sectioning. Higher apertures also increase the resolving power of the optical microscope.\u003c\/span\u003e\u003c\/p\u003e\u003cp class=\"MsoNormalCxSpFirst\"\u003e\u003cstrong style=\"mso-bidi-font-weight: normal;\"\u003e\u003cspan lang=\"ES\"\u003eCompatibility:\u003cbr\u003e\u003c\/span\u003e\u003c\/strong\u003eMAGUS Bio 290T biological microscope\u003c\/p\u003e\u003cp class=\"MsoNormalCxSpFirst\"\u003e\u003cstrong style=\"mso-bidi-font-weight: normal;\"\u003e\u003cspan lang=\"ES\"\u003ePackage:\u003cbr\u003e\u003c\/span\u003e\u003c\/strong\u003e\u003cspan lang=\"ES\"\u003eDIC turret condenser\u003cbr\u003e\u003c\/span\u003e\u003c!--[endif]--\u003e\u003cspan lang=\"ES\"\u003e10x\/20x DIC slider compensators\u003cbr\u003e\u003c\/span\u003e\u003cspan lang=\"ES\"\u003e40x\/100x DIC slider compensators\u003cbr\u003e\u003c\/span\u003e\u003c!--[endif]--\u003e\u003cspan lang=\"ES\"\u003ePolarizing filter\u003cbr\u003e\u003c\/span\u003e\u003c!-- [if !supportLists]--\u003e\u003cspan lang=\"ES\" style=\"mso-bidi-font-size: 10.0pt; mso-bidi-font-family: Arial;\"\u003eCase\u003c\/span\u003e\u003c\/p\u003e","brand":"MAGUS","offers":[{"title":"Default Title","offer_id":52888799215959,"sku":"85108","price":2999.96,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0552\/6198\/6860\/files\/85108_magus-dic290-attachment-set_00.jpg?v=1772207740","url":"https:\/\/astrotelescopios.com\/en-efta\/products\/juego-de-accesorios-magus-dic290","provider":"Astro Telescopios","version":"1.0","type":"link"}
