Customized micro-nano optics

The customized micro-nano optics(CMN) center at SVG Optronics offers a full service from design and manufacturing up to the characterization of micro-nano optical elements for EUV to FIR applications and their processing and assembly in whole systems.
 
 
The CMN center either proceeds according to your design guidelines or creates a design for manufacturing your application.           

CMN center has cooperated with the key-lab of Soochow University  for the fabrication of  large aperture pulse compressed gratings,with NILT in Denmark for e-beam lithography of nano-structures.
