Achromatic Microscope Objective Set 4X 10X 40X 100X

This set includes four achromatic objective lenses for biological microscopes: 4X (NA 0.1, working distance 18 mm), 10X (NA 0.25, working distance 7 mm), 40X (NA 0.65, working distance 0.53 mm), and 100X (NA 1.25, working distance 0.13 mm). All lenses feature a standard RMS thread (20.2 mm mounting diameter) and are designed for use with a 160 mm tube length and 0.17 mm cover glass thickness. Constructed with precision metal cores for durability and optical stability, they deliver consistent chromatic aberration correction across magnifications.
