Microscope achromatic objective lens Color: B Type: Microscope achromatic objective lens for biological microscope Tube length: 160 mm Standard glass thickness: 0.17 mm Magnifications available: 4X, 10X, 40X, 100X Mounting size: 20.2 mm Material: Copper to improve conversion rates Key benefits Accurate, lowaberration imaging: Achromatic design reduces color fringing and improves image clarity for routine biological observation and educational use. Ready compatibility: 20.2 mm mounting size and 160 mm tube length make the objective compatible with microscopes built to these common biological standards. Optimized for standard slides: Designed for use with the standard 0.17 mm glass thickness to maintain focus and optical performance with standard cover slips. Range of magnifications: Available in 4X, 10X, 40X, and 100X to cover widefield overview through power detail without changing optical systems. Durable construction: Copper material in the objective body supports stable mechanical performance and contributes to improved conversion rates. Function and performance Purposebuilt achromatic optics deliver improved contrast and reduced chromatic error across the visible spectrum, supporting clearer observation of stained and unstained preparations. The specified tube length of 160 mm ensures the correct optical spacing for microscopes designed to that standard, preserving intended focal relationships. Mounting size 20.2 mm provides a secure and precise fit for compatible objective turrets. Compatibility and sizing Use with biological microscopes that accept 20.2 mm objective mounts and a 160 mm tube length. Designed for standard slide and cover glass preparations using 0.17 mm thickness. Practical applications Classroom and teaching labs: Ideal for demonstrations and student practicals where multiple magnifications are needed for plant sections, simple organisms, and prepared slides. Research and inspection: Suitable for routine laboratory observations, slide examination, and inspection of microstructures in materials science or quality control. Hobbyist microscopy and field study: Useful for entomology, botany, and hobbyist slide preparation where reliable achromatic performance and common mount compatibility are required. What it solves Eliminates frequent misfit and focus problems by matching the 20.2 mm mount and 160 mm tube length standard. Reduces chromatic distortions that can obscure detail in samples, improving the usefulness of basic light microscopy workflows. Provides a set of magnification options to minimize the need for multiple incompatible optics.
