Largan Precision makes the tiny camera lenses that go inside smartphones and other devices.
Largan Precision makes the tiny lens modules that sit inside smartphone cameras. When you take a photo with your phone and it looks sharp, there is a good chance a stack of small plastic lenses made by Largan is doing the focusing. The company also makes optoelectronic parts for projectors and other camera-based devices.

The business is simple to describe but hard to do well. A phone camera needs several lenses stacked in a tube, each one ground and shaped to near-perfect precision, then assembled into a module the size of a fingernail. Making one is hard. Making millions of them that all work the same way, cheaply and without defects, is much harder. That manufacturing skill is Largan's real product. Phone makers are Largan's main customers, and they buy lenses by the hundreds of millions. The company's fortunes rise and fall with how many phones the world buys and how fancy their cameras are. When phone makers add more lenses per phone or move to higher-end cameras, Largan sells more valuable parts. When phone sales stall, so does Largan. The lens business is fiercely competitive, with rivals in China and elsewhere pushing on price. Largan's edge has been precision and scale, but it has faced pressure as phone makers look for cheaper suppliers and try to design more of the camera themselves. The company has also pushed into car cameras and other optical markets to reduce its reliance on phones.
Largan is based in Taichung, Taiwan, and has been a quiet giant of the optics world for decades. Its stock has long been one of the most expensive in Taiwan, a sign of how much investors value its manufacturing know-how. The simple version: if the world keeps putting cameras in everything, Largan wants to make the lenses inside them.
