On account of their thickness, such samples cannot be observed with inverted Axiovert microscopes and LD objectives, contrary to the examination of cell cultures in transparent vessels. The upright Axioskop 2 FS makes it possible to immerse the objective into a medium contained, e.g., in a Petri dish and examine the specimen from above. Focusing of the Axioskop 2 FS acts on the nosepiece instead of the stage (FS = Fixed Stage).These objectives are, of course, also used for transmitted-light microscopy. One example is the draining of electrical potential from cells. “Achroplan” water immersion objectives are specially adapted to requirements in electrophysiology (patch-clamp technique), in intravital microscopy, in microcirculation studies, in the examination of vital brain sections and other thick specimens. In these techniques, some fundamental conditions have to be satisfied: Superb optical performance and transmission, slender form, front part of special material and long working distance. All Water Achroplan objectives have fields flattened across a diameter of 20 mm. They allow all contrasting methods, including high-resolution differential interference contrast (DIC). Thanks to their high numerical apertures, they not only provide excellent images but also are ideal for fluorescence - not least because of the use of special glass types that are highly transmissive to the excitation light. Further, these objectives are suitable for the \"INFRAPATCH\" method at wavelengths up to 780 nm (special IR versions are available). The slender front part of the objective and the long working distance of these objectives provide sufficient space for the specimen to be well accessible to all microtools (patch-clamp electrodes, microinjection capillaries etc.). It is possible to implement big positioning angles to minimize self-capacitance in patch-clamp potential draining. Moreover, the slender front part barrel is made of special, insulating plastics of extremely low self-capacitance. The material is inert, i.e. it does not release metal ions to the surrounding medium; it is corrosion-proof, chemically resistant and of minimum thermal conductivity.\u003c\/p\u003e\n\n\u003cp\u003e\u003cem\u003e\u003cstrong\u003eTransmittance curve：\u003c\/strong\u003e\u003c\/em\u003e\u003c\/p\u003e\n\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0636\/5888\/5199\/files\/spectrum.png?v=1757680613\" alt=\"\"\u003e\u003c\/p\u003e","brand":"Carl Zeiss","offers":[{"title":"Default Title","offer_id":42816575242319,"sku":"zeiss 420967-9900","price":1400.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0636\/5888\/5199\/files\/Zeiss_W_N-ACHROPLAN_40x0.75_0_420967-9900.jpg?v=1763191599"},{"product_id":"zeiss-plan-apochromat-63x1-4-oil-ph3-440761-9905-phase-contrast-objective","title":"Zeiss Plan Apochromat 63x1.4 Oil Ph3 440761-9905 Phase Contrast Objective","description":"\u003cul\u003e\n\u003cli\u003e\u003cem\u003e\u003cstrong\u003eZeiss Plan Apochromat 63x1.4 Oil Ph3 440761-9905 Phase Contrast Objective \u003c\/strong\u003e\u003c\/em\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cem\u003e\u003cstrong\u003eItem no.:440761-9905\u003c\/strong\u003e\u003c\/em\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cem\u003e\u003cstrong\u003ePhase contrast objective\u003c\/strong\u003e\u003c\/em\u003e\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003e\u003cstrong\u003eMagnification: 63x\u003c\/strong\u003e\u003c\/em\u003e\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\u003cem\u003e\u003cstrong\u003eNumerical Aperture (NA): 1.4\u003c\/strong\u003e\u003c\/em\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cem\u003e\u003cstrong\u003eImmersion medium：Oil \u003c\/strong\u003e\u003c\/em\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cem\u003e\u003cstrong\u003eRMS thread \u003c\/strong\u003e\u003c\/em\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cem\u003e\u003cstrong\u003eCondition: Used, Excellent condition.

important for all contrast methods: brightfield, darkfield, phase contrast, DIC, fluorescence, Pol. They feature high resolving power and brilliant, rich-contrast, completely flat images for observation and documentation. Their high transmission of wavelengths from the near UV range (\u0026gt;40% starting at 340nm) and the use of glass types of low autofluorescence makes these objectives ideal for epi-fluorescence microscopy. Further special-purpose members of the family are EC Epiplan-Neofluar objectives for reflected-light work, the EC Plan-Neofluar Antiflex objective for reflection contrast, and EC Plan-Neofluar Pol objectives for the requirements of polarizing microscopy.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e","brand":"Carl Zeiss","offers":[{"title":"Default Title","offer_id":46380063686735,"sku":null,"price":400.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0636\/5888\/5199\/files\/IMG_3206_1.jpg?v=1786343516"},{"product_id":"zeiss-achroplan-63x-0-90-water-immersion-microscope-objective-lens","title":"Zeiss ACHROPLAN 63x 0.90 Water Immersion Microscope Objective Lens","description":"\u003cp\u003eZeiss ACHROPLAN 63x 0.90 Water Immersion Microscope Objective Lens 440067\u003c\/p\u003e\n\u003cp\u003eRMS thread\u003c\/p\u003e\n\u003cp\u003eClean glass, free of scratches, haze, or optical defects, Used, in perfect optical condition\u003c\/p\u003e","brand":"Carl Zeiss","offers":[{"title":"Default Title","offer_id":46510732705871,"sku":null,"price":1250.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0636\/5888\/5199\/files\/IMG_4115.jpg?v=1787899288"}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0636\/5888\/5199\/collections\/IMG_0367.jpg?v=1771727691","url":"https:\/\/chengtuoptics.com\/collections\/zeiss-obectives.oembed?page=2","provider":"Chengtu Optics","version":"1.0","type":"link"}
