Helium-Neon (HeNe) Lasers

Helium-Neon (HeNe) lasers are highly stable gas lasers renowned for their excellent beam quality, long-term reliability, and low-noise performance. Operating primarily at 632.8 nm (red), HeNe lasers provide a highly coherent, linearly polarized output, making them ideal for precision alignment, metrology, interferometry, holography, spectroscopy, and scientific research applications.

Compared to diode lasers, HeNe lasers offer superior beam stability, lower divergence, and exceptional pointing accuracy, making them the preferred choice for demanding optical experiments and industrial measurement systems.
