The weighted base design ensures the assembly remains firmly in place during use, even when gooseneck arms are extended and repositioned — eliminating the tipping and shifting that can occur with lightweight or unweighted stands. Three M6 threaded ports allow simultaneous mounting of up to three Schott gooseneck arms or compatible accessories, enabling multi-angle illumination configurations from a single base. This makes the 158.340 an ideal solution for inspection benches, dissection stations, and quality control workstations where flexible, freestanding fiber optic illumination is needed independently of a microscope stand. Compatible with Schott M6-threaded gooseneck light guides and accessories from the KL series illumination system.
