The integrated iris diaphragm provides stepless NA adjustment, making it exceptionally versatile across imaging modalities: at full aperture it delivers maximum resolution and light collection for fluorescence and high-resolution brightfield imaging, while stopping down the iris reduces background haze and improves contrast for darkfield, oblique, or thick specimen work. At 60x, it offers a practical balance between the wide field of view of lower magnifications and the resolving power of 100x oil objectives — ideal for applications where both field coverage and fine detail are important. Plan Fluor optical correction ensures flat-field performance and broad fluorescence transmission across UV and visible wavelengths.\u003c\/p\u003e\n\u003chr\u003e\n\u003cp\u003e\u003cstrong\u003e🔎 Typical Applications\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eHigh-resolution fluorescence imaging (widefield, TIRF, and structured illumination)\u003c\/li\u003e\n\u003cli\u003eBrightfield and phase contrast at 60x with variable depth of field\u003c\/li\u003e\n\u003cli\u003eDarkfield and oblique illumination microscopy\u003c\/li\u003e\n\u003cli\u003eLive cell imaging requiring a balance of field of view and resolution\u003c\/li\u003e\n\u003cli\u003ePathology, cytology, and microbiology at oil immersion magnification\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003chr\u003e\n\u003cp\u003e\u003cstrong\u003e📊 Key Specifications\u003c\/strong\u003e\u003c\/p\u003e\n\u003ctable\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eSpecification\u003c\/th\u003e\n\u003cth\u003eDetails\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eMagnification\u003c\/td\u003e\n\u003ctd\u003e60x\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eImmersion Medium\u003c\/td\u003e\n\u003ctd\u003eOil\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOptical Correction\u003c\/td\u003e\n\u003ctd\u003ePlan Fluor (fluorite)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eIris Diaphragm\u003c\/td\u003e\n\u003ctd\u003eYes (stepless NA adjustment)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMicroscope Type\u003c\/td\u003e\n\u003ctd\u003eCFI infinity-corrected (upright and inverted)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePart Number\u003c\/td\u003e\n\u003ctd\u003eMRH02601\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCountry of Origin\u003c\/td\u003e\n\u003ctd\u003eJapan\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCondition\u003c\/td\u003e\n\u003ctd\u003eNew\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003chr\u003e\n\u003cp\u003e\u003cem\u003eUniversity and institutional purchase orders are welcome.
