NILT Standard Stamps are stamps with fixed patterns defined by NILT.
The Wire Grid Polarizer Standard Stamp is ideal for production of wire grid polarizers by nanoimprint lithography for test purposes. The stamp features a large active area of
12 mm x 12 mm with 50 nm lines and spaces - the 50 nm lines appear as grooves on the stamp. The standard stamp is suitable for both thermal and UV NIL by the use of an intermediate polymer stamp copy of the standard stamp.
- Cost-effective stamp for testing of both NIL and wire grid polarizers
- 50 nm wide grooves with 50 nm spacing
- Fast delivery time, typically 3 weeks
