Engineers who design optical systems for a living specify optical components on a regular basis. A well-specified optic controls only the necessary parameters. Unfortunately, the specifications on drawings often do not consider the nuances of the measurement process, resulting in discrepancies between what the designer thought they were specifying and what the optical shop is measuring. This often results in components that are over specified and more expensive than necessary, or worse, components which are underspecified and do not work for the intended application. This talk will look at some widely used optical surface specifications and provide guidance on how to use them properly to minimize the ambiguity between the customer and the supplier.
