The Anti-Reflective Standard Stamp is a large area standard stamp in Nickel based on moth-eye like structures. The three types differ in stamp size and active area.
-
Anti-reflective moth-eye surface structures
-
Stamp size up to 300 mm x 300 mm
-
Reduction of reflectivity to below 0.5%
-
Different stamp sizes and active areas
-
Fast delivery time of typically 3 weeks
The AR effect is achieved by modification of the surface topography on sub-wavelength scale. The AR nanostructures make use of the bio-inspired moth-eye effect. The surface topography creates a graded index profile, reducing visual reflectance of a surface with n=1.5, to air with n=1, from 4% down to below 0.5%.
