Engineering Guidance
Choose the window around transmitted wavefront and environment
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.
