Original Transmission Elements

Can you measure the entire surface of the spherical lens? We can measure the entire surface.


We own 30 types of domestic Transmission Elements (“TEs”) with a shape accuracy of PV lambda / 20 or less, a total of 86 lenses. These highly accurate TEs and interferometers are combined to process high-precision lenses. If our requested TEs cannot measure the requested spherical lens, we will design and manufacture a new internal TEs.
