Dimensions and shapes vary depending on models
Please note that R-31004 is now obsolete. A recommended replacement model is R-31007, however, check the specifications of each model to determine the most suitable replacement.Newport offers a complete line of Helium-Neon (HeNe) Laser products, at the wavelengths of 543 nm (Helium-Neon (HeNe) Lasers - Green 543 nm), 632.8 nm, 1.52 µm, and 3.39 µm (Helium-Neon (HeNe) Lasers - Infrared), that combine both high performance and affordability. All Newport HeNe lasers are CE compliant except R-32413, R-31425 and R-32734. The red HeNe laser product family offers TEM00 mode at 633 nm. All are available in either linear or random polarization. With an emphasis on satisfying a variety of applications and budgetary needs, we offer a variety of power levels ranging from 0.5 mW to 35 mW. 35 mW HeNe laser is one of the most powerful commercial HeNe lasers available. This product family offers some of the highest power levels available in production HeNe lasers. Utilizing enhanced designs and superior optical components these lasers deliver unsurpassed operational stability and lifetimes. The mirror quality and performances are optimized to result in the highest quality HeNe lasers available in the market. These high-performance lasers are supported by a one-year warranty and are available off-the-shelf. Newport also offers a Helium-Neon frequency and intensity stabilized laser (Helium-Neon (HeNe) Laser - Frequency and Intensity Stabilized).
We have models whose outputs are either polarized or randomly polarized. Due to the random fluctuation of the polarization state of the beam, it is not recommended to use a polarizer with a random polarization laser for applications where polarized light is required.
Laser Mounts provide convenient mounting of cylindrical lasers to positioners, rods, and tables. Please see Cylindrical Laser Mounts.
