Plan Achromatic Objective Set 4X 10X 40X 100X for Biological Microscope Metal Parts Accessories Key benefits Broad coverage of magnification needs with a single set: 4X for scanning, 10X for low power observation, 40X for detailed viewing, and 100X for magnification tasks. Plan achromatic optical design reduces chromatic and field curvature errors to deliver a flatter, more uniformly focused image across the field of view. Durable metal housings and precision threads ensure stable mounting, long service life, and consistent optical alignment during routine use. Simple, modular upgrade or replacement option for biological microscopes used in teaching, laboratory, and hobby settings. What this product does and how it helps Provides a matched series of objectives that cover common laboratory and educational magnifications, simplifying setup and reducing the need to switch between incompatible components. Improves image quality compared to generic objectives by addressing color fringing and offaxis focus variation, making it easier to evaluate prepared slides and small structures. Metal construction minimizes wear and mechanical play in the objective turret, maintaining parfocal behavior and reliable focusing across sessions. Key attributes Magnifications: 4X, 10X, 40X, 100X Optical type: Plan achromatic objective design Material: Metal objective housings and mechanical parts for strength and durability Function: Biological microscope objectives designed for visual observation and basic imaging workflows Form factor: Standard screwin objective style compatible with common objective turrets Compatibility and installation Designed to be used with biological microscopes that accept standard screwin objectives and objective turrets. Check existing turret thread and clearance before installation. Each objective installs like a standard microscope objective; tighten securely by hand and verify parfocal alignment after fitting. Performance notes The plan achromatic design improves flatness across the image field and reduces color fringing for clearer observation of stained slides, thin sections, and small specimens. Metal mechanical parts deliver stable, repeatable mounting and resistance to deformation from frequent use. Practical use scenarios Classroom microscopy: A complete set for teaching labs to demonstrate specimen scanning, cell structure observation, and progressive magnification techniques. Research and sample preparation: Routine inspection of botanical sections, prepared histology slides for educational research, and detailed observation of small invertebrates or microstructures. Industrial and hobby inspection: Visual examination of microfabricated parts, printed circuit patterns, fibers, and other small components that require variable magnification and reliable optics. What to check before Verify that your microscope accepts screwin objectives of standard size and that there is enough clearance for the 100X objective when installed. Confirm whether immersion is required for 100X in your application and ensure you have the appropriate immersion medium and cleaning supplies. This objective set offers a practical optical upgrade for biological microscopes where improved field flatness, consistent mounting, and a complete range of common magnifications are required.
