IVS* Sapphire Windows (*Interferometrically Verified Sapphire)
Optical
Performance: A plane wave shall be distorted no more than ¼ wave in a single pass, verified by HeNe Interferogram**.
Parallelism: Less than one second of arc, verified in Internal Frizeau Fringe Interferogram**
Orientation: Each IVS Sapphire Window is individually x-ray oriented and corrected to within +/- 30 minutes of axis. Actual orientation of each finished window can be supplied to +/- 3 minutes or arc.
Axial/Planar Orientation: Available in Zero Degree (optical axis of the sapphire perpendicular to the window face), or 90 Degree (optical axis in the plane of the window).
** All interferograms are made at 632.8 nm with our Zygo Mark II with 6" aperture, microcomputer data reduction and fringe analysis.
