HIGH PRECISION SUBSTRATES F. SYNCHROTRON RADIATION

NOK - Flat Surface Substrates

Ok GmbH produces flat surface substrates with nanometer form accuracy for synchrotron radiation based on the typical polishing-process with pitch.

(Cooperation associates for ionic beam shaping of precision surfaces with nanometer accuracy: IOM e.V. Leipzig (www.iom-leipzig.de) and Nano Technologie Leipzig (www.ntgl.de))



  

We offer:
Substrates for mirrors, gratings and monochromators (spherical and flat surfaces)
produced from Silicon (100) and (111), Zerodur® (Schott AG), ULE® (Corning Ltd.), Silica and other materials



 

Precision Substrates we produce customized substrates

Our substrate surfaces are characterized by:
Micro roughness up to 0,2 nm RMS
Deviation of shape (Slope-Error) in the range of 0,1 arcsec rms in cross- and longitudinal-direction
