• Custom-made products for which reflected wavefront and transmitted  wavefront accuracy is certified by measurements with a Zygo GPI XP-6"  laser interferometer system.

• Used as precision parallel plates for beam splitters or similar  applications that require accuracy for both reflection and transmitted  wavefronts.

• The reflection and transmitted 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.
