Carl Zeiss, an optician and German industrialist, is credited with creating the Carl Zeiss optical lens. Carl Zeiss is known across the world for producing high-quality optical instruments, industrial measurement equipment, and medical devices. In Jena, Germany, he established the ZEISS workshop in 1846 to manufacture microscopes and other optical devices. Zeiss and Nokia have been working together for a very long time. Several Nokia smartphones come equipped with Carl Zeiss optics. Yet, Nokia's decline is not halted by this optics feature.
