According to "C:\Users\gques\Nextcloud\GQuEST\Layout_Mockups\readout_FCs_1_2_and_3.svg" I'm estimating for one cavity we need the following items below.
1550:
-5 HR/mount
-Flip Mount
-Fiber output coupler - DONT HAVE
-1550 fiber
-1550 Fast
-1550 slow PD 
-1550 BS - have
-Lens for MM
-posts/forks x10

775:
-5 HR/mount 
-775 Fiber output coupler x2 
-775 long fiber 
-775 BS 
-775 Fast 
-775 slow PD 
-posts/forks x10
-2 lens for MMing cavity

I have gone through the supplies and found everything on the list and placed them on the optics table (see attached photo), except for 1550 fiber coupler. We do not have enough of these items for a second (3rd total) filter cavity to be built. I am just getting this ready so I can order anything we don't have and immediately need for progress to be made after I get back from 4th of july break. We will need to do another large order to start progress on the 3rd filter cavity.

Additionally, I currently have Ian/Briana's fast 775 PD set aside to be FC2 REFL PD. When you guys are ready for one please take the one in transmission of the first filter cavity. 

For the placement of the new sled that should arrive on Wednesday, I am planning on placing it cattycorner to the existing 2x4 on the same optics table. They can't be placed side by side without a bit of overhang. I have cleared this space already. Please do not place new optics here as they will quickly need to be moved.
