Product Overview

Specify Quartz Double-Surface Optical Flat by aperture, surface accuracy and mounting

The model table keeps each available grade separate because aperture, thickness, surface accuracy and parallelism directly change how the reference optic performs.

Confirm the required grade on each face and the parallelism requirement; the two available face-grade combinations are not interchangeable.

Performance considerations

The model table keeps each available grade separate because aperture, thickness, surface accuracy and parallelism directly change how the reference optic performs.

Selection and mounting

Confirm the required grade on each face and the parallelism requirement; the two available face-grade combinations are not interchangeable.

Need a different diameter, tolerance or coating?

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