Assembly apparatus for the transmitter. An optical fibre is glued into a channel in the transmitter body with an unglued length facing the LEDs. The unglued ferrule is connected to a six axis stage (SmarAct SMARPOD 70.42) which scans the fibre position across the LEDs to find the optimal position. The ferrule is then glued to the transmitter body in this position and its connection to the stage is severed
