• Custom-made products for which reflection wavefronts accuracy is  certified by measurements with a Zygo GPI XP-6" laser interferometer  system.

• Used as flat substrates for total-reflection mirrors, Newton  plates, and other applications demanding reflection wavefront accuracy.

• The reflection wavefront accuracy of these products is  certified by interference fringe photos and three-dimensional analysis  data. These documents are provided along with the product.

• Also available are coated master optics. However, the accuracy  guarantee applies only to the substrate. Accuracy may vary from surface  accuracy after coating.

• Master optics with pits are also available.

注意

• Also available are master optics with apertures larger than ø150 mm. See "Large aperture optics".

• Certified accuracy for flat substrates for total-reflection  mirrors normally indicates reflection wavefront accuracy. Certified  accuracy for precision parallel plates for windows and wedge substrates  normally indicates transmitted wavefront accuracy. Certified accuracy  for precision parallel plates for laser mirrors or beam splitters  normally indicates the accuracy of both reflection and transmitted  wavefronts.
