d. "Technology" as follows: 1. "Technology" "required" for the coating and treatment of optical surfaces to achieve an 'optical thickness' uniformity of 99.5% or better for optical coatings 500 mm or more in diameter or major axis length and with a total loss (absorption and scatter) of less than 5 x 10-3; For the purposes of 6.E.3.d.1., 'optical thickness' is the mathematical product of the index of refraction and the physical thickness of the coating. 2. "Technology" for the fabrication of optics using single point diamond turning techniques to produce surface finish "accuracies" of less (better) than 10 nm rms on non-planar surfaces exceeding 0.5 m2; LASERS
