Product Overview

Specify K9 High-Precision 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.

Select both-face flatness and parallelism together when the flat will be reversed, stacked or used as a transmissive reference.

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

Select both-face flatness and parallelism together when the flat will be reversed, stacked or used as a transmissive reference.

Need a different diameter, tolerance or coating?

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