• 🏭 M Plan optical correction for flat, uniform field across the full image area
• 🔩 RMS thread, 210mm tube length — compatible with Nikon Optiphot and other 210 TL reflected light microscopes
• ✅ Excellent condition — flawless optics, inspected and verified

🔧 Product Description

The Nikon M Plan 100x ELWD (SKU 79237) is part of Nikon's M Plan series of finite tube length reflected-light objectives, engineered for high-magnification surface imaging on opaque specimens. The ELWD design provides meaningfully more working distance than standard 100x objectives, reducing the risk of contact with specimens and enabling inspection of slightly recessed or elevated features. The M Plan optical correction delivers a flat, well-corrected field suited to both visual inspection and camera-based imaging. With an RMS thread and 210mm tube length, this objective is a direct fit for the Nikon Optiphot Reflected Light microscope and compatible 210 TL systems. This listing is for a unit in excellent condition with flawless optics — a strong value for labs seeking a proven Nikon objective at well below new cost.
