The objective is infinity-corrected. It can be used to study samples 1 µm and smaller in a wide field of view. It is suitable for analyzing biological fluids in the laboratory, such as blood or urine (determining the number of leukocytes, red blood cells, casts).\u003c\/p\u003e\u003cp\u003eThe MAGUS MA20 20x\/0.40 objective is used with 10x to 20x eyepieces. The objective corrects color aberration for blue and red, spherical distortion for green, and field curvature for 65% of the field of view diameter. During observations, use a coverslip 0.17 mm thick.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCompatibility:\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eMAGUS Bio 230B Biological Microscope\u003c\/li\u003e\n\u003cli\u003eMAGUS Bio 230BL Biological Microscope\u003c\/li\u003e\n\u003cli\u003eMAGUS Bio 230T Biological Microscope\u003c\/li\u003e\n\u003cli\u003eMAGUS Bio 230TL Biological Microscope\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eSpecifications:\u003c\/strong\u003e\u003cbr\u003eLens material: optical glass\u003cbr\u003eOptical system: achromatic\u003cbr\u003eCompatible tube length, mm: infinity (∞)\u003cbr\u003eMagnification, x: 20\u003cbr\u003eAperture: 0.40\u003cbr\u003eWorking distance, mm: 2.61\u003cbr\u003eParfocal distance, mm: 45\u003cbr\u003eCoverslip thickness, mm: 0.17\u003cbr\u003eSpring mechanism: −\u003cbr\u003eOil immersion: −\u003cbr\u003eBody material: copper\u003cbr\u003eThread type: WJ 4\/5\"*1\/36\"\u003c\/p\u003e","brand":"MAGUS","offers":[{"title":"Default Title","offer_id":52888775622999,"sku":"82927","price":66.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0552\/6198\/6860\/files\/82927_magus_ma20_infinity_achr_objective_00.jpg?v=1772207527","url":"https:\/\/astrotelescopios.com\/en-uk\/products\/objetivo-magus-ma20-20%d1%85-0-40-0-17-infinity-achromatic","provider":"Astro Telescopios","version":"1.0","type":"link"}
