Bullet point notes on the filter cavity sled as things are moving around as we prepare for 775 nm.

-Particle count since super optics in use: 0/0/0

-To allow for 775 light transmission I have moved the 1550 TRANS PD to be on the opposite side it was previously. See attached photo.

-780 HR steering mirror and 50:50 BS set up, as well as the NIR basler camera to see 780 transmission. Location set up for 780 TRANS PD when they arrive.

-NIR basler camera confirmed working on pylon viewer. Had not been previously tested. Waiting on a 3D printed mount from Daniel to put it on the table. Daniel updated the print to include slots for ventilation.

-1811 PD installed for 775 REFL. Note that this PD is not made for 775 and will be inefficient. Hopefully it will suffice. Additionally, we will need an ND filter in this path depending on how much 775 power we put into the filter cavity. In its current configuration there is <1 mW. 1550 saturation power is 55 uW though. Will likely need at least an OD1 ND.

-Particle count at end of morning work: 0/0/0
