Foreword

This standard is equivalent to ISO 13694.2000 "Optical and optical instrument laser and laser related equipment laser beam power (energy) Test Method for Density Distribution" and Technical Corrigendum Cor1.2005 (English version). Many applications of lasers involve the use of near-field and far-field power (energy) density distributions of laser beams. The power of the laser beam (energy The characteristic of the density distribution is the spatial distribution of the irradiation power (energy), and it is the lateral distribution of a specific plane perpendicular to the direction of propagation. Generally, the power (energy) density distribution of the laser beam changes with the propagation direction. This standard was proposed by the State Food and Drug Administration. This standard is under the jurisdiction of the National Standardization Sub-Technical Committee of Medical Optics and Instruments (SAC/TC103/SC1). This standard was drafted. Hangzhou Medical Device Quality Supervision and Inspection Center of the State Food and Drug Administration. The main drafters of this standard. Huang Dan, Sun Yu, Ye Yueshun, Han Jiancheng. Optical and optical instrument laser and laser related equipment Test method of laser beam power (energy) density distribution

1 Scope

This standard specifies the method for measuring the power (energy) density distribution and defines the laser power (energy) density distribution function on a given plane Number of characteristic parameters. The methods specified in this standard are suitable for detecting and describing the characteristics of continuous laser and pulsed laser beams used in optical and optical instruments.
