Lens Making

レンズ (Renzu)


During World War II, Japanese factories manufactured lenses for warships and other military uses. Lens manufacturers took the work very seriously because defective lenses could be fatal. After the war, Japan desperately needed to reconstruct. Building on their lens-making know-how, Japan eventually developed some of best lenses in the world.
