OPTIX manufactures precise radial standards - "Test plates" pursuant to DIN, providing for the control of the surfaces during the manufacturing of the optical elements.

The radii vary from R=0.6 to R=ad infinitum, and the precision of the optical surface reaches lambda/20.The control of the standards is made through precise Fisba-interferometers.

OPTIX has a large list of continuously updated Test plates available that the customers may use while designing their optical elements and systems.
