You should have ordered items 2-6 (long lead-time itmes from Thorlabs and Jenoptik).
Now order all other items (lines 7-120) EXCEPT line item 66 (Equipment Solutions; this refers to a critical part of the z-focusing mechanisms and we are trying to converge on an even faster design).
Order quantities as indicated in the spreadsheet (sometimes these diverge from the quantities indicated in the quotes)

PMT Shutters Modification
This modification allows the addition of shutters to each PMT channel, placed right in front of the PMT. They have a ~10 ms opening transit time, and should block very little detection light while open (not more than a percent or two).
Shutter and driver purchase quote: This quote is for the uni-stable (normally closed) shutter. This may no longer be available, except with a minimum qty order (recent change announced on Vincent website). If so, we think that the bistable version (NS25B1T0L-VED) should fit OK and work fine. It might actually open faster, so may be preferrable overall.
Modification instructions: The asphere lens can be removed from the Thorlabs lens tube mount and mounted in the new part. Once the shutter is mounted, the wires will need to be soldered to the connector provided with the VED24 driver. Shutter driver settings note:
The settings for an NS25S type shutter operating with a VED24 driver are as follows, for the ‘Function Switches’ and ‘Pulse Duration’: Switch 1 = Up, Switch 2 = Down, Switch 3 = Down, Switch 4 = Up, & Pulse Duration = 4 [[[Switch 1 = LOCAL (‘REMOTE’ is down), Switch 2 = 18VDC, Switch 3 = Uni-stable Mode, Switch 4 = Pulse Set 1, & Pulse Duration = 20msec]]]
Shop drawings for new part and two part modifications.
Wire cap fabrication files: Use silicone, tape, or make nice wire caps using rapid prototyping method of choice. Included are STEP file, STL file (for 3d printing), or DXF file (for laser-cut acrylic).
