IO GigE camera installation on the PSL is complete
optic
absolute distance from IO_AB_L4
focal length and beam diam.
IO_AB_L4
0
fl = 1145.6mm
IO_lens3
43.4cm
fl = -618.2mm
IO_lens4
123.3cm
fl = 720.2mm
IOGigE1
163.1cm
beam diameter = 1.9mm
IOGigE2
245.5cm
beam diameter = 1.9mm
gouy phase is around 88deg
beam waist size between GigE cameras is 150um
at 30W input to the IMC, the IO beam at IO_lens3 = 42mW
this beam is attenuated using beam splitters in the beam path between lenses
at 30W input there is 105uW on each GigE camera
