Technical data

Determination of the wavelength of a laser with an optical grating

Article no: P1410901

Principle

When a laser beam falls on a grating, interference causes intensity minima and maxima to be formed behind the grating, and the wavelength of the laser beam can be determined from these positions.

Benefits

Curriculum-relevant DEMO Experiment in optics
Equivalence to the corresponding student experiment
Stable optical bench
Compact, simple construction
