Description

Special suitable compact monochromatic light source for interference and diffraction experiments. As a result of the linear polarisation, this laser is also suitable for experiments on the rotation of the plane of polarisation and on light modulation. With stand rods for the use on the optical bench or on the base plate for laser optics. Caution:
The laser conforms to class 2 safety requirements as defined by EN 60825-1:2003-10.
Always pay attention to safety instructions in the instruction manual and local regulations on laser safety when conducting experiments.
