An HeNe laser typically has a minimum beam diameter of 2 w0 = 1 mm. The wavelength of the HeNe laser is λ = 0.63 μm = 0.63 × 10 −3 mm. The full divergence angle calculated by Eq. (2.5) is roughly 10 −3 radians = 1 milliradian (i.e., 0.06°). At a distance of 10 m from the laser, the beam diameter will thus be only 1 cm.

Suited for many optics demonstrations such as refraction, interference and communication. 2020-08-17 A helium-neon laser, usually called a HeNe laser, is a type of small gas laser. HeNe lasers have many industrial and scientific uses, and are often used in laboratory demonstrations of optics. Its usual operation wavelength is 632.8 nm, in the red portion of the visible spectrum . 2021-04-07 These include 633 nm Red (standard and high power models), 543 nm Green, 594 nm Yellow, 612 nm Orange, 1.15, 1.52 micron or 3.39 micron Infrared or our Multi-Line and Frequency/Intensity Stabilized lasers. The REO Infrared (IR) HeNe lasers line are available in TEM00 output mode with 500:1 linear polarization at: 1.15 micron; 1.52 micron; 3.39 micron Helium-neon laser constructio The Helium-Neon Laser, short HeNe-Laser, is one of the most common used laser for allignement, reference laser and optics demonstrations. Its most used wavelength is at 632.8nm (red) The wavelength can thus be found using the equation To three digits, this is the wavelength of light emitted by the common He-Ne laser.

The laser emits light with a wavelength of 632.82 nm in air. The wavelength is completely stable and can be used as a reference. The laser light is emitted in a well-defined direction as a thin light ray. Suited for many optics demonstrations such as refraction, interference and communication.

These Lasos Helium-Neon (HeNe) Lasers have a robust mechanical design, excellent beam quality and long service life of up to 30.000 hours. For ease of system integration Lasos HeNe lasers are designed with tough cylindrical housing that precisely aligns with the beam and provides great protection for the laser tube and internal electronics. Of course, regardless of its wavelength, the beam of a laser must be precisely controlled and directed. Lenses, windows and mirrors supplied by Esco Optics play an important role in assuring this precision.
