Subject: OMC breadboard/plate measurement dimensions 

We have measured the dimensions and mass of the OMC glass plates/breadboards:

S/N Mass (g) Length (mm) Width (mm) Height (mm) Notes
01 6146 449.66 149.85 41.42, 41.42  for LLO
02 6126 449.66 149.97 41.32, 41.32  for LHO
03 6143 449.76 149.98 41.39, 41.43  
04 6139 449.78 149.81 41.40, 41.40  for 3IFO
05 6132 449.76 150.03 41.27, 41.31 corner chip, front-bottom-left*
06 6138 449.84 149.71 41.42, 41.42  
  • * orientation is relative to "front" face, i.e. long-short face with S/N on it, with S/N upright.
  • Height measurements were made twice, once at each end.
  • TMeasurements of 03, 05, 02, and 06 were done in the open in the OMC lab.  This was not thought to be too much of an issue since the plates
    are already covered with particulate matter from the tissue paper that they were wrapped in. 
    Measurements of 04 and 01 were done on the optics table, under the clean room enclosure.

Note by Koji:

  • The scale of the bake lab was used. (Max 60kg, Min resolution of 1g)
  • The dimensions were measured by a huge caliper which Jeff brought from Downs.
  • S/N 01, 03, 04 look pretty similar. They should be the primary candidates.
