The Dartmoor Pony Moorland Scheme (DPMS) was established in 1988 and is administered by the Dartmoor Pony Society and the Duchy of Cornwall, as well as being supported by the Dartmoor National Park.

The Dartmoor Pony has been granted Rare Breed status. Dartmoor ponies are native to Britain, but are also seen in other parts of the world including the USA, Continental Europe,
Anti-reflective coating microelectronic photolithography to help reduce image distortions associated with reflections off the surface of the substrate. Different types of antireflective coatings are applied either before or after the photoresist, and help reduce standing waves, thin-film interference, and specular reflections. The simplest form of anti-reflective coating was discovered by Lord Rayleigh in 1886. The optical glass available at the time tended to develop a tarnish on its surface with age, due to chemical reactions with the environment. Rayleigh tested some old, slightly tarnished pieces of glass, and found to his surprise that they transmitted "more" light than new, clean pieces. The
