Installing a New Lamp
7. Place the new lamp into the socket, remembering to only touch the ceramic-
socket. (Replacement lamps are available from Navitar, part # 8-16165.) Put
the safety guard back in place and secure it with the two screws. Carefully push
the whole base plate of the lamp back into the projector.
ATTENTION!
Make sure that the lamp is properly pushed into the reflector and
secure it with the designated screws. Despite the high quality of the OSRAM HTI-
lamps, burner positions may vary due to production. Therefore, we recommend
you readjust the lamp after each exchange (see below).
Lamp Adjustment
The socket for the lamp module in the SUPERNOVA 10K projector is secured at
three points so that the lamp can be adjusted in every direction.
1. Ignite the lamp and insert an empty slide (no picture) in the slot. The lighter
side of the frame must face the lamp.
2. Wait about one minute for the lamp to reach maximum brightness. You will see
a white projection on the screen. The screen will not be evenly white. Slight
variations of color might even be visible. You will need to move the brightest
spot (hot-spot) to the center of the projection. We recommend two people work
together to adjust the lamp to move the hot-spot.
3. One person, using a lux meter,
should place the measuring
probe precisely in the center of
the projection. The second
person, behind the projector,
should turn screw J1 so the light
density gets higher in the center
of the projection. The person
reading the lux meter can help
direct the person adjusting the
screw. Once the maximum light
density is obtained with screw
J1, adjust screw J2 in the same
manner. Finally, adjust screw J3
in the same way.
4. When all three screws are adjusted, repeat the procedure for fine adjustment.
