Test methods for laser beam widths, divergence angles and beam propagation ratios.

Terms and conditions for Customized compilation izo standards Contact us Accessibility. For example, applications of high-energy laser weapons and lidars require precise knowledge of how much transmitted power actually illuminates the target.

The Oso width is often used in applications that are concerned with knowing exactly how much power is in a given area. Find Similar Items This product falls into the following categories.

Retrieved June 3, Take the smart route to manage medical device compliance. This is the beam diameter definition that is used for computing the maximum permissible exposure to a laser beam. Stigmatic and simple astigmatic beams. Document s cited in this standard. Accept and continue Learn more about the cookies we use and how to change your settings. A beam may, for example, have an elliptical cross section, in which case the orientation of the beam diameter must be specified, for example with respect to the major or minor axis of the elliptical cross section.

The beam width can be measured in units of length at a particular plane perpendicular to the beam axis, but it can also refer to the angular width, which is the angle subtended by the beam at the source. Purchase More information add to basket. You may experience issues viewing this site in Internet Explorer 9, 10 or The simplest way to define the width of a beam is to choose two diametrically opposite points at which the irradiance is a specified fraction of the beam’s peak irradiance, and take the distance between them as a measure of the beam’s width.

The angle between the maximum peak of radiated power and the first null no power radiated in this direction is called the Rayleigh beamwidth. More information add to basket.
