When manufacturing lenses for polarizing objectives, internal stresses are avoided so that the optics do not produce birefringence or affect observation.\u003c\/p\u003e\u003cp\u003eThe MAGUS SFR50 50x has a resolution limit of 0.39 µm. It is designed for an infinity-corrected optical system with a parfocal distance of 45 mm. It is not necessary to cover the sample with a coverslip for observation.\u003c\/p\u003e\u003cp\u003eA plan achromatic objective corrects aberrations: chromatic in red and blue, spherical in green, and geometric for 90% of the image area. The objective provides a wide and sharp field of view. It is suitable for coupling to a system with a digital camera or wide-field eyepieces with a 22 mm field of view. A 10x\/22 mm eyepiece will provide a 0.44 mm field of view. The image will be equally sharp in the center and at the edges.\u003c\/p\u003e\u003cp\u003eA useful microscope magnification for this objective will be between 350x and 700x. To obtain the necessary magnification, use eyepieces with a magnification of 7x to 15x. Eyepieces with lower magnification will not allow effective examination of the sample. Likewise, an eyepiece with a magnification higher than 15x will not provide new data.\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 by aberration correction degree: achromatic plan\u003cbr\u003eTube length: infinity corrected (∞)\u003cbr\u003eContrast technique: polarized light\u003cbr\u003eMagnification, x: 50\u003cbr\u003eAperture: 0.70\u003cbr\u003eWorking distance, mm: 3.67\u003cbr\u003eParfocal distance, mm: 45\u003cbr\u003eCoverslip thickness, mm: no coverslip\u003cbr\u003eSpring mechanism: +\u003cbr\u003eImmersion: −\u003cbr\u003eBody material: copper\u003c\/p\u003e","brand":"MAGUS","offers":[{"title":"Default Title","offer_id":52888789778775,"sku":"83454","price":353.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0552\/6198\/6860\/files\/83454_magus-sfr50-50h-plan-l-pol-objective_00.jpg?v=1772207634","url":"https:\/\/astrotelescopios.com\/en-uk\/products\/objetivo-magus-sfr50-50%d1%85-0-70-plan-l-pol-0","provider":"Astro Telescopios","version":"1.0","type":"link"}
