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
