Quarter Wave Plate Specifications

  • Quarter wave Plates are suggested for B7. A proposed specification is among FE IPT documents. We proposed these to begin a dialog with FE in July 2006. At that time there was a f2f meeting with FE and Sci here in Cville. A reply was posted to edm 14 months later calling for review and approval of these specifications; I am unaware that this was discussed in a science or cal group meeting. Let us proceed: is the proposed bandwidth and center agreed? How accurately does it need to be a quarter wave? A memo on the SMA device is attached at the bottom of this page.
