✅ Core Features
-
Plan Semi-Apochromat (Semi APO) Correction: Delivers exceptional color fidelity and sharpness across the entire field of view, eliminating chromatic aberration and field curvature for professional-grade imaging.
-
Infinity Corrected Optical Design: Fully compliant with international infinity microscope standards, ideal for modern biological microscopes and direct replacement for Olympus objectives.
-
Long Working Distance: Extended working distance for each magnification, especially for low-power lenses, providing more space for sample manipulation and observation.
-
Multi-Layer Anti-Reflection Coating: Full optical lenses with advanced AR coating minimize light reflection, maximize light transmittance, and deliver bright, high-contrast, color-accurate images.
-
Durable Pure Copper Construction: Sturdy copper body ensures long-term stability, wear resistance, and reliable performance in laboratory, research, and industrial environments.
-
Universal Compatibility: Standard RMS thread interface fits seamlessly with most infinity-corrected biological microscopes, including Olympus CX and BX series, making it an ideal replacement for imported objectives.
-
Adapter Compatibility: Can be converted to M25, M26, M27, or SM1 threads with a compatible adapter ring for expanded system integration.
✅ Wide Applications
Perfect for biological research, clinical laboratories, university research institutions, food inspection, machine vision, pet hospitals, and industrial inspection. Suitable for observing cells, tissues, bacteria, and other biological specimens, and serves as a reliable replacement for imported Olympus objectives.
✅ Package Includes
1 x Selected Magnification Plan Semi-Apochromat Infinity Corrected Microscope Objective Lens (with dust-proof storage box)
✅ Important Note
-
The 100X objective requires immersion oil for optimal high-resolution imaging.
-
This objective is designed for infinity-corrected biological microscopes only. Please confirm your microscope's optical system and RMS thread compatibility before purchase.
