6.5.4 Lamp O ptimization
Since the light is coupled into the light rod by means of a mirror, the position of the mirror to-
gether with the actual lamp properties determine the light yield.
During the
Lamp Optimization procedure, the light output of the active lamp in dependance of the
tilting angle of the mirror is measured, and the optimized mirror position for the lamp is deter-
mined.
The procedure should be performed subsequently for both lamps. The optimised positions are
stored independently for both lamps, so that after setting the lamp lift in motion and thus changing
the active lamp, the mirror position is adjusted accordingly.

This procedure optimizes the coupling of the active lamp into the optical system of
the projector and is immediately triggered by selecting the command Lamp
Optimization. During this procedure, the display gets dark for about 30seconds.
 Use the cursor keys to highlight Lamp Optimization
 Press ENTER to select.
The following message box is displayed:

The results of the optimization adjustments are saved individually for both lamps. Therefore after
changing the active lamp, no optimization procedure is required, the lamp will automatically be
brought into the former determined best position.
However, when replacing the lamp, it is recommended to select Lamp Optimization,
since the new lamp has different parameters and therefore has to be adjusted anew.
