With a numerical aperture of 0.70 and a working distance of 0.5mm, it delivers strong resolution and light-gathering capability at 40x magnification for routine brightfield, histology, and cytology applications. The SPlan (Semi-Plan) optical design provides a noticeably flatter and more uniformly sharp field compared to standard achromats, with excellent color fidelity across the visible spectrum. Mounts via the standard RMS thread and is compatible with Olympus BHT, BHTU, BHS, CHS, CHT, and other 160mm RMS microscope systems.\u003c\/p\u003e\u003chr\u003e\u003cp\u003e\u003cstrong\u003e🔎 Typical Applications\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eHistology and pathology slide review at 40x magnification\u003c\/li\u003e\n\u003cli\u003eCytology and hematology on Olympus BH2 series microscopes\u003c\/li\u003e\n\u003cli\u003eCell biology and tissue culture observation\u003c\/li\u003e\n\u003cli\u003eRoutine brightfield and phase contrast microscopy\u003c\/li\u003e\n\u003cli\u003eUpgrading or replacing objectives on legacy 160mm tube length microscopes\u003c\/li\u003e\n\u003c\/ul\u003e\u003chr\u003e\u003cp\u003e\u003cstrong\u003e📊 Key Specifications\u003c\/strong\u003e\u003c\/p\u003e\u003ctable\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003cth\u003eSpecification\u003c\/th\u003e\n\u003cth\u003eDetails\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eModel\u003c\/td\u003e\n\u003ctd\u003eSPlan 40x\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCatalog Number\u003c\/td\u003e\n\u003ctd\u003e1-LB551\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMagnification\u003c\/td\u003e\n\u003ctd\u003e40x\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eNumerical Aperture (NA)\u003c\/td\u003e\n\u003ctd\u003e0.70\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eImmersion Medium\u003c\/td\u003e\n\u003ctd\u003eDry\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWorking Distance (WD)\u003c\/td\u003e\n\u003ctd\u003e0.5 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTube Length\u003c\/td\u003e\n\u003ctd\u003e160 mm (finite)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eObjective Thread\u003c\/td\u003e\n\u003ctd\u003eRMS\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCompatible Microscopes\u003c\/td\u003e\n\u003ctd\u003eOlympus BHT, BHTU, BHS, CHS, CHT and other 160mm RMS systems\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\u003ctr\u003e\n\u003ctd\u003eCountry of Origin\u003c\/td\u003e\n\u003ctd\u003eJapan\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\u003c\/table\u003e\u003chr\u003e\u003cp\u003e\u003cem\u003eUniversity and institutional purchase orders accepted.
