Spherical optics

zuend

Spherical optics with sizes 0.2 to 10.0mm are produced in following production types: single part production, small batch series and mass production. Surface form deviation can be measured and documented.
Spherical optics with sizes >10.0 to 20.0mm are produced in following production types: single part production, small batch series and mass production. Surface form deviation can be measured and partly documented.
