NILT Standard Stamps are stamps with fixed patterns defined by NILT. These stamps are ideal for testing and process optimization.
The Anti-Reflective Standard Stamp is a large area and cost-effective functional standard stamp in Nickel with a graded index profile and with a continuously changing effective refractive index.
