4X Achromatic Biological Objective

This 4X achromatic objective is built for biological microscopy systems using the conventional 160mm tube length standard. It provides low-magnification imaging with high optical fidelity, leveraging an achromatic doublet design to minimise chromatic and spherical aberrations. The lens incorporates precision-ground glass elements with broadband anti-reflective coating. Its 4X magnification enables efficient specimen overview and stage navigation, serving as the foundational objective in multi-objective turret setups. Designed for durability and consistent optical alignment, it mounts securely via standard RMS threads.
