Strain-free objectives do not create birefringence and do not affect the result of sample observation.\u003c\/p\u003e\u003cp\u003eA low 2.5x magnification objective is combined with eyepieces from 10x to 25x to create useful microscope magnifications ranging from 35x to 70x. If eyepieces with lower magnification are used, it will not be possible to study the sample optimally; eyepieces with a magnification greater than 25x will not be effective, as the optical system will not show new details. The resolution limit is 3.92 µm.\u003c\/p\u003e\u003cp\u003eThe SFR2 objective model is equipped with plan achromatic optics. It creates a wide field of view by correcting geometric aberration in more than 90% of the observed area: a focused image will be obtained both in the center and at the edge of the field. It is recommended to make observations using a digital camera or a wide-field eyepiece. With a 10x\/22 mm eyepiece, the field of view has a diameter of 8.8 mm. With such a field, the sample can be effectively studied: the desired area can be quickly located and the approximate grain size in minerals can be calculated by changing the eyepiece. The sample can be examined with or without a cover slip.\u003c\/p\u003e\u003cp\u003eThe objective is designed for an infinity-corrected optical system; the parfocal distance is compliant with the DIN standard.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCompatibility:\u003c\/strong\u003e\u003cbr\u003eMAGUS Pol 850 polarizing microscope\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eSpecifications:\u003c\/strong\u003e\u003cbr\u003eLens material: optical glass\u003cbr\u003eObjective class according to aberration correction degree: plan achromatic\u003cbr\u003eTube length: infinity-corrected (∞)\u003cbr\u003eContrast technique: polarized light\u003cbr\u003eMagnification, x: 2.5\u003cbr\u003eAperture: 0.07\u003cbr\u003eWorking distance, mm: 11\u003cbr\u003eParfocal distance, mm: 45\u003cbr\u003eCover slip thickness, mm: the objective is designed to work with samples with or without a cover slip\u003cbr\u003eSpring-loaded mechanism: −\u003cbr\u003eImmersion: −\u003cbr\u003eBody material: copper\u003c\/p\u003e","brand":"MAGUS","offers":[{"title":"Default Title","offer_id":52888789713239,"sku":"83453","price":299.95,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0552\/6198\/6860\/files\/83453_magus-sfr2-2-5h-plan-l-pol-objective_00.jpg?v=1772207633","url":"https:\/\/astrotelescopios.com\/en-eu\/products\/objetivo-magus-sfr2-2-5%d1%85-0-07-plan-l-pol","provider":"Astro Telescopios","version":"1.0","type":"link"}
