The integrated iris diaphragm provides stepless NA adjustment from 0.5 (lower contrast, greater depth of field) to 1.3 (maximum resolution and light collection). This makes it exceptionally versatile: at full aperture it delivers the resolving power needed for fine structural detail in fluorescence and brightfield imaging, while stopping down the iris reduces background haze and improves contrast for darkfield, oblique, or thick specimen work. Plan Fluor optical correction ensures flat-field performance and broad fluorescence transmission across UV and visible wavelengths. An essential objective for labs requiring flexibility across multiple imaging modalities at high magnification.\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 100x with variable depth of field\u003c\/li\u003e\n\u003cli\u003eDarkfield and oblique illumination microscopy\u003c\/li\u003e\n\u003cli\u003eMicrobiology: bacterial morphology, flagella, and fine structural detail\u003c\/li\u003e\n\u003cli\u003ePathology, cytology, and hematology 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\u003e100x\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\u003eNumerical Aperture\u003c\/td\u003e\n\u003ctd\u003e0.5–1.3 (variable, iris diaphragm)\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\u003eMRH02902\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.
