While standard 100x BD objectives provide only 0.39mm of working distance, this ELWD variant extends that to 2.0mm—more than five times the clearance. This extended working distance enables inspection through thicker cover slips, manipulation of samples under observation, and compatibility with specialized sample chambers or environmental controls. The BD Plan optical formula ensures flat-field correction across the entire field of view and superior chromatic correction, making it ideal for quantitative imaging, photomicrography, and critical dimensional metrology in industrial and research environments.\u003c\/p\u003e\n\n\u003chr\u003e\n\n\u003cp class=\"MsoNormal\" style=\"font-family: 'Segoe UI Emoji', sans-serif;\"\u003e\u003cstrong\u003e🔎 Typical Applications\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003cp class=\"MsoNormal\" style=\"font-family: 'Segoe UI Emoji', sans-serif;\"\u003e\n• Semiconductor wafer inspection and defect analysis\u003cbr\u003e\n• Materials science and metallurgical examination\u003cbr\u003e\n• Biological sample imaging through thick mounting media\u003cbr\u003e\n• Quality control and dimensional measurement\u003cbr\u003e\n• Photomicrography and digital imaging workflows\u003cbr\u003e\n• Research applications requiring sample manipulation during observation\n\u003c\/p\u003e\n\n\u003chr\u003e\n\n\u003cp class=\"MsoNormal\" style=\"font-family: 'Segoe UI Emoji', sans-serif;\"\u003e\u003cstrong\u003e📊 Key Specifications\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003ctable border=\"1\" cellpadding=\"8\" cellspacing=\"0\" style=\"border-collapse: collapse; width: 100%; font-family: 'Segoe UI Emoji', sans-serif;\"\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 50%;\"\u003e\u003cstrong\u003eSpecification\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 50%;\"\u003e\u003cstrong\u003eDetails\u003c\/strong\u003e\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\u003eOptical Design\u003c\/td\u003e\n\u003ctd\u003eBD Plan (Bright Field, Plan Achromat)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWorking Distance\u003c\/td\u003e\n\u003ctd\u003e2.0mm (ELWD)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTube Length\u003c\/td\u003e\n\u003ctd\u003e210mm (Nikon Industrial Standard)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eThread Standard\u003c\/td\u003e\n\u003ctd\u003eRMS (Royal Microscopical Society)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCondition\u003c\/td\u003e\n\u003ctd\u003eExcellent – optically and mechanically sound\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\/table\u003e\n\n\u003chr\u003e\n\n\u003cp class=\"MsoNormal\" style=\"font-family: 'Segoe UI Emoji', sans-serif;\"\u003e\u003cem\u003eUniversity purchase orders welcome.
