In addition to production equipment developed inhouse, we also use special state-of-the-art cutting machines.
Using superior manufacturing facilities and production lines, some of which were developed and built in-house, we cut and grind our mirrors to the exacting specifications of our customers - reliably and with the expertise resulting from decades of experience.

When inspecting the finished products, we don't just rely on the human eye, but employ our own LANG camera test equipment which was specially designed in-house for spherical and aspherical mirror glasses. These tests allow us to offer our highly comprehensive warranty.

All relevant production data, including customer-specific item numbers, are printed on the back of each mirror glass produced by LANG, ensuring that every product is uniquely identified and matched to each individual customer.This process provides for seamless lot tracking at all times.
