| 1. | More important, though, is the fineness of the gratings.
 
  | 
 | 2. | The first such gratings have periods of 200 to 400 nanometers.
 
  | 
 | 3. | The company commercializes hyperspectral imaging systems based on volume Bragg gratings.
 
  | 
 | 4. | Because of this, gratings are commonly used in monochromators and spectrometers.
 
  | 
 | 5. | In order to overcome this limitation holographic gratings were developed.
 
  | 
 | 6. | Gratings are also used extensively in research into visual perception.
 
  | 
 | 7. | The GLV uses six ribbons as the diffraction gratings for each pixel.
 
  | 
 | 8. | The idiyappam is served with coconut gratings and coconut milk.
 
  | 
 | 9. | Holographic gratings may exhibit less scattered light than ruled gratings.
