Product Overview

Specify Sapphire High-Precision Plane Window by aperture, surface accuracy and mounting

The series is intended for applications that need sapphire durability but cannot accept ordinary protective-window flatness or surface quality. It is useful for exposed cameras, industrial inspection heads and optical systems subject to cleaning or particulate contact.

Check crystal orientation and polarization sensitivity, especially in coherent or polarization-resolving systems. Use a compliant mount because concentrated edge stress can degrade transmitted wavefront performance.

Performance considerations

The series is intended for applications that need sapphire durability but cannot accept ordinary protective-window flatness or surface quality. It is useful for exposed cameras, industrial inspection heads and optical systems subject to cleaning or particulate contact.

Selection and mounting

Check crystal orientation and polarization sensitivity, especially in coherent or polarization-resolving systems. Use a compliant mount because concentrated edge stress can degrade transmitted wavefront performance.

Need a different diameter, tolerance or coating?

Custom substrate materials, dimensions, angular tolerances and coating bands can be reviewed for prototype and production quantities.
