Welcome to our Helium-Neon Laser online catalog!

Cascade Laser Corporation has recently begun providing Helium Neon (HeNe) laser systems and power supplies.

Helium Neon (HeNe) lasers are renowned for their precision and reliability, making them indispensable tools in various scientific and industrial applications. Commonly producing wavelengths of 632.8 nm (red), 543.5 nm (green), 594.1 nm (yellow), and 1523 nm (infrared), HeNe lasers typically offer power outputs of a few milliwatts. They are highly valued for their superior beam quality, excellent wavelength stability, and long operational life, which are critical for precision measurements and research.
HeNe lasers are widely used in fields such as metrology, holography, spectroscopy, and alignment due to their coherent and monochromatic light output. Despite the advent of newer laser technologies, HeNe lasers continue to be favored for their reliability, cost-effectiveness, and straightforward design and maintenance. Their enduring popularity stems from their ability to deliver consistent performance in precision-dependent tasks.

NOTE: This is not a comprehensive list of all the models we sell; these are just the most popular.
