The \"SL\" designation stands for Super Long Working Distance — at 13.0mm WD with a 100X magnification and NA of 0.55, this objective occupies a class of its own. Most 100X objectives offer working distances of 0.1–0.2mm; the M Plan Apo SL delivers 13mm of clearance, enabling non-contact inspection of deep features, recessed surfaces, tall components, and specimens that cannot tolerate close objective proximity.\u003c\/p\u003e\n\u003cp\u003eThe apochromatic correction eliminates chromatic aberration across the visible spectrum, producing sharp, color-accurate images even at the edges of the field. Infinity correction ensures compatibility with modern tube lens systems and allows optical accessories (filters, beamsplitters, polarizers) to be inserted in the infinity space without focus shift. With a resolving power of 0.5µm and focal depth of 0.9µm, this objective resolves fine surface features and defects with precision.\u003c\/p\u003e\n\u003cp\u003eThis is a brand-new objective — a significant value at this price point for a Mitutoyo M Plan Apo SL.\u003c\/p\u003e\n\u003chr\u003e\n\u003cp\u003e\u003cstrong\u003e🔎 Typical Applications\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eNon-contact semiconductor and wafer inspection\u003c\/li\u003e\n\u003cli\u003eMEMS, microelectronics, and PCB defect analysis\u003c\/li\u003e\n\u003cli\u003ePrecision metrology and surface roughness measurement\u003c\/li\u003e\n\u003cli\u003eInspection of tall or recessed features on industrial components\u003c\/li\u003e\n\u003cli\u003eMachine vision and automated optical inspection (AOI) systems\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\u003ePart Number\u003c\/td\u003e\n\u003ctd\u003e378-813-3\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eManufacturer\u003c\/td\u003e\n\u003ctd\u003eMitutoyo\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSeries\u003c\/td\u003e\n\u003ctd\u003eM Plan Apo SL (Super Long Working Distance)\u003c\/td\u003e\n\u003c\/tr\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\u003eNumerical Aperture (NA)\u003c\/td\u003e\n\u003ctd\u003e0.55\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWorking Distance (WD)\u003c\/td\u003e\n\u003ctd\u003e13.0mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFocal Length\u003c\/td\u003e\n\u003ctd\u003e2mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eResolving Power\u003c\/td\u003e\n\u003ctd\u003e0.5µm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFocal Depth\u003c\/td\u003e\n\u003ctd\u003e0.9µm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOptical Correction\u003c\/td\u003e\n\u003ctd\u003eInfinity corrected, apochromat\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eIllumination Type\u003c\/td\u003e\n\u003ctd\u003eBrightfield (visible wavelength)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eThread\u003c\/td\u003e\n\u003ctd\u003eM26\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eField of View (Ø24 eyepiece)\u003c\/td\u003e\n\u003ctd\u003eØ0.24mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eReal FOV (1\/2\" chip camera)\u003c\/td\u003e\n\u003ctd\u003e0.05 x 0.06mm\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 accepted.
