[VIDEO] Specifying a CGH (Computer-Generated Hologram) 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
