Universal 20.2 mm 20X Plan Objective for Biological Microscopes Key benefits Easy compatibility: Standard 20.2 mm interface fits most biological microscope stands, allowing quick upgrades or replacements without modifying the microscope. Reliable imaging: Infinite optical system with a plan objective corrects spherical aberration and distortion, producing parallel light paths and sharp images across the field without edge blurring. resolution detail: 20X magnification provides clear detail for cell structures and small particulates while serving as an effective intermediate step between low and power. Practical design for scientific work: Balances a wide, bright field for overview observation and sufficient enlargement for focused study of fine structures. Features and attributes Function: 20X objective designed for professional observation, suitable for initial imaging or further magnified study. Compatibility: Standard 20.2 mm interface compatible with a wide range of biological microscope brands and models. Optical system: Infinite optical design with plan correction to minimize distortion and maintain even focus across the image plane. Performance: Delivers resolution, edgetoedge sharpness suitable for laboratory and teaching applications. Construction: Precision optical design for consistent imaging performance in routine and extended use. Typical applications Educational laboratories: Classroom demonstrations and student practicals where consistent, easytouse optics speed up lesson setup and improve viewing for groups. Research and teaching in cytology and microbiology: Observing cell morphology, prepared slides, and stained specimens at an intermediate magnification. Environmental sample analysis: Examining water samples, particulates, and microorganisms where clear midrange magnification is required before switching to higher power. Technical summary Interface size: 20.2 mm standard Magnification: 20X Optical type: Infinite system, plan objective Recommended use: Education, research, cytology, microbiology, environmental observation
