This objective lens set provides a complete range of magnifications for versatile microscopy work: 4X, 20X, 40X, 60X, and 100X. Key benefits Wide magnification range for flexible imaging from lowpower overview to power detail. Springloaded protection on the higher magnification lenses prevents accidental contact with slides, reducing the risk of slide damage during focusing. Coated optical elements reduce reflections and improve contrast for clearer, more usable images. Advanced 100X design increases numerical aperture, improving lightgathering and resolving fine specimen details at magnification. Features and performance Included magnifications: 4X, 20X, 40X, 60X, 100X. Optical coatings applied to lens elements to minimize stray light and maximize image contrast. Mechanical springloaded mechanism on higher magnification objectives to protect slides and specimens during adjustments. Designed for microscopy applications that require a full set of objectives for routine observation and more demanding magnification work. Function and compatibility Intended as an objective lens package for use with compatible microscopes and standard objective nosepieces. Suited for both routine observation and detailed inspection where a range of magnifications is required. Compact set that can serve as a replacement or upgrade to existing objective collections. Typical applications Educational laboratories: classroom demonstrations and student microscopy where quick changes between magnifications are needed. Research and teaching: preparing and examining biological samples, plant sections, and prepared slides that require contrast imaging. Industrial inspection and quality control: examination of materials, small components, and surface features that require varied magnifications and reliable slide protection. Set summary A practical, performanceoriented objective lens package covering 4X through 100X, with coated optics, slideprotecting springloaded design on higher magnifications, and an advanced 100X objective optimized for improved numerical aperture and magnification imaging.
