Optical Components

IVS Sapphire Windows


Optical Performance: A plane wave shall be distorted no more than 1/4 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.
