What happened in China For decades, the industrial lens market was a quiet Japanese oligopoly. In 2019, Kowa Lenses, Computar (CBC Group), and Fujifilm together accounted for 22.32%, 15.94%, and 8.12% of global industrial lens revenue respectively — more than 46% of the market held by three Japanese-heritage brands. The product category was considered technically demanding enough to discourage serious competition from lower-cost manufacturing bases. That assumption is now being stress-tested. Chinese optical manufacturers, concentrated in the Pearl River Delta manufacturing corridor around Dongguan and Shenzhen, have spent the better part of a decade investing in mid-range industrial optics — the lenses used in automated quality inspection lines, logistics sorting systems, and factory machine vision setups. These are not the exotic high-precision optics used in semiconductor lithography. They are the workhorses of industrial automation: reliable, interchangeable, and increasingly commoditised. The clearest signal of where this is heading comes from…
