Partlist
This section contains details of all the parts used on the robot unit. That includes the X-and Y axis, the gripper unit and the different viewing systems.

Optics used in this system:
| Folding mirror | SH 34 00 57 15x20x2 mm |
| Relay lens | MG 01 LAT 013 f=20mm Ø12.5mm (u=27.6mm v= 73mm) |
Coherent bundles
Two coherent bundles are used to relay the image from the sky viewing probes to the CCD autoguider.
| Mobile sky viewing probe | Dolan-Jenner ISO 596 | length: 96" | throughput: 41% |
| Fixed (off axis) sky viewing probe | Dolan-Jenner ISO 536 | length: 36" | throughput: 45% |
Zeroset Switches:
In the whole instrument switches of the opto coupler type are used. They use an infrared light diode and a detecting diode. When the switch is activated there's a voltage drop from 5V to 0. The switch is a standard RS component..................... On each switch there's 4 wires.
Schemes of the circuits can be found in the documentation AF2 technical documentation in the AF2 cupboard.
