These lasers have the same great features as our diode lasers. You will easily recognize this laser as it is packaged it in a brilliant blue acrylic housing which is extremely durable and visually appealing to both industrial and educational users. The helium neon laser with its narrow and stable wavelength stability and long coherence length is ideal for holography and interferometry, AM/FM radio transmission, diffraction, single and double slit experiments. In addition, this laser can be used to conduct regular laser, optics and fiber optic experiments which demonstrate properties such as refraction, reflection, tyndall's light-guiding-in-water experiments, scattering of light, critical angle determination in materials, convergence and divergence of lenses, polarization of light, and measurement of Brewster's angle. 2-year warranty.

Linear Polarization: A type of polarization where the electric field vector oscillates in a single plane along the direction of propagation.

he-ne laser wavelength

The polarization state refers to the orientation and characteristics of the electric field vector of a light wave, describing how the light's electric field oscillates in relation to its direction of propagation. This concept encompasses various types of polarization, including linear, circular, and elliptical, which provide insights into how light interacts with materials and how it can be manipulated for various applications.

Polarizing Filter: An optical device that selectively transmits light waves of a specific polarization while blocking others.

Circular Polarization: A type of polarization where the electric field vector rotates in a helical pattern, maintaining a constant amplitude as it propagates.
