Quality Assurance
We take quality control very seriously: we rely on accurate, widely recognized measurement systems for testing our optics. The following table indicates the accuracy of measurement for the most relevant parameters.
Surface figure: λ/20
Angle: 0,5 arcsec
Radius: 0,01%
Focal length: 0,03%-0,3%
Centration: +/-0,2µm or +/-2 arcsec
Wavelength: +/-0,3nm (190-1100nm)
