When choosing laser safety glasses, several factors you should consider to ensure that you select the appropriate ones for your needs. Here are some key points to keep in mind:
- Determine the laser type and wavelength: Identify the specific laser type and its corresponding wavelength or Nanometer (NM). Laser safety glasses work by blocking specific laser wavelengths, so you need to choose glasses that protect against the laser you'll be working with. You should be able to find this market on the house side of your laser or in the owner's manual.
- Check the optical density (OD): The optical density rating indicates the glasses' ability to block laser radiation. The Higher the number the better the glasses block against the corresponding wavelength. Your required OD will be labeled outside the laser or found in the owner's manual.
- Evaluate visible light transmission: Consider the laser safety glasses' visible light transmission (VLT). VLT refers to the percentage of visible light passing through the lenses. Look for glasses with higher VLT values to allow more visible light transmission while maintaining the required level of laser protection. The higher the VLT, the lighter the lens color will be, allowing a clearer view of the work environment and ensuring greater comfort during extended use.
- Verify the laser safety standards: Look for glasses that meet recognized laser safety standards, such as ANSI Z136.1 in the United States or EN207 in Europe. Compliance with these standards ensures that the glasses have undergone appropriate testing and meet safety requirements.
- Evaluate comfort and fit: Laser safety glasses should fit comfortably and securely. Consider factors such as frame design, weight, and adjustability to ensure a fit and minimize discomfort during use.
