In true CVI fashion they don't have any of the mirrors that we want. I'm not actually certain what they keep in their warehouse but it certainly isn't optics.
Delivery time is going to be 4weeks (make that more like 6) for both the output mirror (another 2" diameter BS1- 99%) and the beam splitter for the Mach Zehnder (2" BS1 50%). I'm going to put through the order for them now.
Edit - That's the order through Techmart now (5/18).
