Luminous intensity (photometer)

Principle

The experiment, which must be conducted in a completely darkened room, is demanding both with reference to the experimental abilities of the students and also with regard to their care and exactness in making observations.

Benefits

• Multifunctional light box – All-in-one: Can be used for geometric optics on the table, colour mixing and on an optical bench
• Extension with others sets at anytime, no additional light sources needed, recognition value for students

Tasks

How can the luminous intensity of light sources be determined? To compare the brightness of several light sources with a photometer.
