200mm Tube Lens

These infinity-corrected tube lenses are designed for use with infinity-corrected objectives from all major manufacturers, including the dry, oil immersion, and physiology microscope objectives sold by Thorlabs. Designed for high-resolution imaging, biomedical, machine vision, and laser scanning applications, these lenses can be aligned in pairs to create relays, combined with objectives to create different effective magnification ratios at a scientific camera, used as drop-in replacements for tube lenses in existing systems, or integrated into DIY Cerna® Microscopes and other home-built microscopy setups to generate high-quality images.
