The multiple beam lamp allows
numerous demonstra-tions in the areas of ray and
wave optics when used with the equipment set for
optics on magnetic boards, basic set (U14600) and
supplementary set (U14601). The demonstrations
include casting of shadows, chromat-ics, reflection
laws, refraction laws, total reflection, minimum angle of
deflection in a prism, ascertaining the focal length of
mirrors and lenses, lens laws and aberrations.
1. Safety instructions
Caution: Lamps heat up during extended periods of
operation.
Do not touch the glass bulb of the lamp with your
bare hands when changing the bulb, for
example. Lamp bulbs are clouded by fat deposits
on the skin.
2. Description, technical data
The device comprises a halogen lamp in a metal
hous-ing lined with magnetic foil. The light source
emits up to 5 narrow beams which are deflected by
rotary mir-rors so as to emerge parallel, convergent or
divergent. Up to 2 divergent light beams whose area
of overlap can be adjusted by means of mirrors are
available on the rear of the multi-beam lamp.

Attach the lamp to the board.
Plug the lamp into a power supply unit, for in-
stance, U11735.
Adjust the beam via rotary mirror 1.
Attach the lamp to the board.
Plug the lamp into a power supply unit, for in-
stance, U11735.
Adjust the beam via rotary mirror 2.
Loosen the screws, remove the round protective
cover (A) and the spacers.
Remove the flat plug (E), loosen the knurled screws
(B), remove the plate (C) and the lamp (D).
Insert a new lamp. Fasten the plate again with
knurled screws such that the lamp can still be
moved.
