The main factors that affect laser beam divergence are the size of the laser beam aperture, the quality of the laser beam optics, and the wavelength of the laser. Other factors such as atmospheric conditions and temperature can also have an impact on divergence.

The solid angle of a laser beam is directly proportional to the beam's intensity. This means that the larger the solid angle, the more spread out the beam is, resulting in a lower intensity. Conversely, a smaller solid angle indicates a more concentrated beam with a higher intensity.

Disclaimer: Given the anti-glare coating on all Felix Gray glasses, we DO NOT recommend attempting to remove scratches from glasses yourself.

For those who haven’t yet purchased their pair of Felix Gray anti-glare, Blue Light blocking glasses, the below will explain how to get scratches out of glasses. In today’s post, we’ll be covering four of the most common scratch-removal methods and touching on some important points consumers should know about each.

Knowing how to get scratches out of glasses using the above methods can save you a ton of money in the long run by extending the lifespan of your specs. But remember, if these tricks for removing scratches from glasses don’t work for you, you can always consult with an eyewear professional. In some cases, the damage to your glasses may be too severe to repair.

Laser beam divergence can be reduced by using high quality optics, such as lenses or mirrors, to shape and control the beam. The size of the laser beam aperture can also be adjusted to reduce divergence. Additionally, using a longer focal length or lower power laser can also help reduce divergence.

Laser beam divergence refers to the spreading out of a laser beam as it travels through space, while solid angle measures the total amount of space that a laser beam covers. In other words, laser beam divergence is a measure of the spread of the beam, while solid angle is a measure of the coverage area.

Laser beam divergence is typically measured in milliradians (mrad) or radians (rad). It can be measured using specialized instruments, such as a beam profiler or a goniometer, which measure the angle at which the beam diverges.
