The Nikon TU Plan Fluor 100x Reflected Light Objective is a high-performance infinity-corrected objective delivering exceptional resolution for EPI (reflected light) microscopy. With a N.A. of 0.90 and 1mm working distance, it resolves fine surface features with outstanding contrast — ideal for demanding industrial inspection, semiconductor analysis, and materials science applications. This unit is a demonstration model in flawless optical condition, offered at significant savings over new pricing. 🔬 100x magnification with N.A. 0.90 for maximum dry-objective resolution 💡 EPI (reflected light) design for opaque and surface-level specimen inspection 🏭 Plan Fluor optical correction for flat, high-transmission field across visible wavelengths 🔩 M25 thread, infinity-corrected — compatible with Nikon infinity-corrected microscopes ✅ Demonstration model — flawless optics, inspected and verified 🔧 Product Description The Nikon TU Plan Fluor 100x (catalog no. MUE12900) is part of Nikon's TU Plan series of reflected-light objectives, engineered for high-NA surface imaging on opaque specimens. At N.A. 0.90, it sits at the top of the dry objective range, delivering the resolving power needed to characterize fine surface structures, defects, and microfeatures. The Plan Fluor optical design ensures excellent field flatness and strong transmission across the visible spectrum, supporting both visual inspection and camera-based imaging workflows. With an M25 thread and infinity-corrected design, it integrates directly with Nikon's broad range of infinity-corrected upright and industrial microscopes. This listing is for a demonstration model in flawless optical condition — a rare opportunity to acquire a premium Nikon objective at well below new cost. 🔎 Typical Applications Semiconductor wafer and die defect inspection at high magnification PCB trace, via, and solder joint analysis Metallurgical microstructure and surface finish examination MEMS and microelectronics surface characterization Precision component quality control and failure analysis Materials science surface imaging 📊 Key Specifications Specification Details Manufacturer Nikon Model / Part Number TU Plan Fluor 100x / MUE12900 Magnification 100x Numerical Aperture (N.A.) 0.90 Working Distance (W.D.) 1.0 mm Thread M25 Optical System Infinity-Corrected Illumination Type EPI (Reflected Light) Optical Correction Plan Fluor Immersion Medium Dry (Air) Condition Demonstration Model — Flawless Optics Country of Origin Japan University and institutional customers are welcome to submit a purchase order.
