TESS - Training and Experiment System

Optics sets with 70 experiments in physics

Phywe provides the following complementary sets of apparatus for the topic of optics, TESS Optics OE 1 and TESS Optics OE 2, as well the supplementary set TESS Optics - Mixing Colours, allowing as many as 34 experiments to be performed. The experiment literature guides students through the experiments themselves in a series of easily understood exercises.

TESS - Optics OE 2 13277-88

Experiments marked with an asterisk * can be performed using only the basic equipment set OE 1
Experiments marked ** require the "Mixing Colours" supplement to OE 1

Equipment

The equipment sets for the subject of optics comprise two complementary sets, plus the “Mixing Colours” supplement. The apparatus in the Mixing Colours set can be stored in a foam inlay inside the storage case for the set TESS Optics OE 1.
