1. Safety instructions

Warning! Lamps become extremely hot when op-
erated for prolonged periods of time.

Do not clean any of the optical components with
aggressive fluids or solvents. This could cause dam-
age!

2. Experiment examples

Experiment 1: Demonstration of various ray
beams
1.1 Equipment:

Optical bench U17150

Experimental lamp U17140

Object holder, shaft-mounted U17000

Fivefold slit from U17040

Convex lens f = +150 mm U17108

Projection screen U17125

3 optical riders 75 mm U17160

1 optical rider 30 mm U17161

Plug-in power supply unit U13900

1.2 Set up

Place the experimental lamp horizontally on the
rail at the 10 cm position.

Place the object holder with five-fold slit horizon-
tally on the rail at the 20 cm position

Place the convex lens at the 25 cm position.

Mount the projection screen on the small rider.

1.3 Procedure

When the convex lens is not used, the ray beam is
divergent.

When the convex lens is placed at the 25 cm posi-
tion we obtain a parallel beam of rays.

When the convex lens is moved away from the light
source a converging beam of rays is produced.

plane mirror
