Specifying a CGH Test

So you'd like to order a CGH (computer-generated hologram)... what's the first step?

In this video, Dr. Jim Burge explains how you can specify a CGH optical test by:
⮞ Describing the test surface prescription and desired measurement accuracy
⮞ Defining the alignment and datum features
⮞ Providing information about your interferometer and available transmission spheres
⮞ Sharing your schedule requirements
