Anti-Reflection – Standard Stamp

NIL Technology offers a wide range of standard stamps with Anti-Reflection (AR) structures. The AR Standard Stamp portfolio contains stamps for making AR structures for both AR in the visible range, as well as in the near infrared range. The standard stamps are offered in different size formats. All stamps can be supplied in larger sizes upon request and in special formats of laser cut from the formats specified below.

The AR structures are based on the moth-eye design, the best of which can reduce the reflectivity from a PMMA surface to below 0.2% in the visible and near infrared range.

The AR standard stamps can be delivered with or without anti-sticking coating.

Note that the AR standard stamps are only for test and product development purposes. A commercial use of the AR standard stamp structures requires a royalty agreement
