In this work a teaching-laboratory device was created for students of secondary schools, academic lyceums and colleges, as well as for students of higher educational institutions to study the phenomenon of internal and external photoeffects and to perform laboratory works in the field of physics optics. The device presents the results obtained on the basis of experiments proving that light consists of a flux of quasi-particle photons. The created device fully demonstrates the most important phenomena of physics, as well as such qualities as safety, ease of use, the possibility of individual work of students, does not require an external energy source and cheapness allow to use this device widely.
