Optical Density (OD): Determine the required OD level based on the laser’s wavelength and power. Consider the laser’s maximum output power and select a barrier that offers a sufficient OD rating to prevent laser radiation from passing through.

Material and Construction: Choose laser barriers made from high-quality materials that are specifically designed for laser safety. Look for barriers constructed with durable, non-reflective materials to minimize the risk of scattered laser radiation.

Size and Coverage: Assess the size of the area that needs protection. Laser barriers are available in various sizes and formats, including panels, curtains, windows, and enclosures. Ensure the chosen barrier adequately covers the intended workspace, blocking any potential laser radiation.

Viewing Conditions: If visibility into the laser workspace is required, opt for laser barriers with appropriate optical properties. Select barriers that maintain optical clarity while providing the necessary protection against laser radiation.

Compliance and Certification: Choose laser barriers that comply with relevant safety standards, such as the American National Standards Institute (ANSI) Z136 series. Look for barriers that have been tested and certified by reputable organizations to ensure their effectiveness and reliability.
