HeNe Laser Module Accessories

1. Overview

HeNe (Helium-Neon) laser module accessories are peripheral components designed to enhance the functionality, precision, and safety of HeNe laser systems. These accessories include optical elements, mounting hardware, power supplies, and beam manipulation tools. HeNe lasers, operating at wavelengths such as 632.8 nm (red), are widely used in scientific research, medical diagnostics, and industrial metrology due to their coherence, stability, and monochromaticity. Accessories play a critical role in optimizing beam alignment, controlling power, and ensuring safe operation.
