Olympus LWD MSPlan 250x Reflected Light Objective🔬 250x magnification — among the highest available for industrial reflected light microscopy🌗 Brightfield illumination with MSPlan flat-field apochromat correction📏 0.8 mm long working distance — exceptional clearance for a 250x objective⚙️ RMS thread — compatible with Olympus BX, GX, MX, and BHM series✅ Excellent condition, same as new — Part No. 1-LM599🔧 Product DescriptionThe Olympus LWD MSPlan 250x is an exceptionally rare ultra-high magnification long working distance reflected light objective, delivering 250x magnification with a 0.90 NA and 0.8 mm working distance. The MSPlan (M Plan Apochromat) optical design provides flat-field correction and superior chromatic aberration-free imaging across the entire field of view — critical at this magnification where any aberration is significantly amplified. With 0.8 mm of working distance, it offers meaningful clearance for a 250x objective, enabling inspection of specimens that would be inaccessible to standard high-magnification objectives. Brightfield illumination provides high-contrast surface imaging for sub-micron feature detection and ultra-fine surface analysis. Infinity corrected and RMS threaded, it integrates with Olympus BX, GX, MX, and BHM series reflected light microscopes. Supplied as a genuine Olympus objective (Part No. 1-LM599) in excellent condition, same as new.🔎 Typical Applications Sub-micron surface feature inspection and ultra-high magnification quality control Advanced semiconductor and IC die-level defect review Precision microelectronics and MEMS device inspection Ultra-fine metallurgical grain structure and surface analysis Research applications requiring maximum magnification in reflected light 📊 Key Specifications Specification Details Magnification 250x Numerical Aperture (NA) 0.90 Working Distance 0.8 mm (Long Working Distance) Contrast Method Brightfield Thread RMS Optical Design MSPlan (M Plan Apochromat, No Coverslip) Tube Length Infinity (∞) Part Number 1-LM599 Condition Excellent — Same as New Country of Origin Japan University and institutional purchase orders accepted.
