What is EN ISO 11146:2019?

EN ISO 11146:2019 is an international standard that provides guidelines for the measurement and evaluation of laser beam parameters. It specifies the methods and procedures for determining the beam diameter, divergence, and propagation characteristics of laser beams. This standard plays a crucial role in ensuring the accuracy and consistency of laser measurements in various applications.

The Importance of EN ISO 11146:2019

EN ISO 11146:2019 is essential in industries where laser technology is widely used. It helps manufacturers and researchers validate their laser systems and ensure they meet the required specifications. By following the guidelines outlined in this standard, it becomes possible to evaluate the quality of a laser beam and assess its suitability for different applications, such as material processing, medical procedures, and telecommunications.

Key Parameters Covered by EN ISO 11146:2019

This standard focuses on several key parameters that are crucial in describing laser beams. These include:

M-squared (M²) - This parameter characterizes the beam quality and determines how close the laser beam is to an ideal Gaussian profile. It provides information about the divergence and focusability of the beam.

Beam Diameter - EN ISO 11146:2019 defines the beam diameter as the region containing a high percentage (e.g., 86.5%) of the total beam power. Accurate measurement of the beam diameter is vital for applications that require precise focusing or tight tolerances.

Divergence - The standard also addresses the measurement of beam divergence, which refers to the spreading of the laser beam over distance. A low divergence indicates a highly collimated beam that remains focused over longer distances.

Compliance and Benefits

Adhering to EN ISO 11146:2019 allows manufacturers, researchers, and end-users to ensure the accuracy and reliability of laser systems. Compliance with this standard enables better control over laser parameters, leading to improved performance and consistent results. Additionally, it provides a standardized approach for comparing different laser systems and establishing compatibility in various applications.
