Method and apparatus for microstructured filters in laminates for light attenuation

A laminate, comprising:

• a first layer, a first material of the first layer having a first refractive index, the first layer including a first surface;
• a first microstructure layer including a first microstructure pattern formed on a first surface of the microstructure layer, a first microstructure material of the first microstructure layer having a first microstructure material refractive index, the first microstructure pattern having first repeating structures with a first predetermined periodicity, the first microstructure layer being disposed on the first surface of the first layer;
• a second layer, a second material of the second layer having a second refractive index, the second layer being disposed adjacent to the first surface of the first microstructure layer;
• a third layer, a third material of the third layer having a third refractive index, the third layer being disposed adjacent to the second layer on a side opposite the microstructure layer;
• and
• a second microstructure layer, a second microstructure material of the second microstructure layer having a second microstructure material refractive index, a first surface of the second microstructure layer including a second microstructure pattern formed on the first surface of the second microstructure layer, the second microstructure pattern having second repeating structures with a second predetermined periodicity, the second microstructure layer being disposed between the first microstructure layer and the second layer, the first surface of the second microstructure layer being disposed adjacent to the second layer.
