Laser Protective Glasses

Our laser welding protective glasses provide protection for your eyes against the dangerous lasers from automatic and manual laser welding machines, as well as laser cutting devices. Laser systems are classified by specialists based on the wavelength and power of the beams they produce, thus determining the level of risk they pose to users.

Because laser beams are highly concentrated, they can be very hazardous. Even a small amount of laser light can cause permanent damage to the eyes, burn the retina, and necessitate strict government controls regarding exposure.

Most of the danger from laser light stems from heat; however, at certain wavelengths (not the one we use: 1076 nanometers infrared), there are also dangerous optical chemical effects. With high-power lasers, even reflected light can harm the eyes. Yet, the majority of the risk associated with laser beams is due to their coherence, which concentrates a large amount of energy onto a small spot on the retina.

Infrared lasers, which are mostly used in our manual laser welding machines, pose a particular risk because they are not visible and do not trigger the eye’s blink reflex. Powerful lasers in the 400-1400 nanometer range penetrate the eye and heat the retina. At other wavelengths, the cornea and lens absorb energy, leading to cataracts or burns. The retina lacks pain receptors; hence workers exposed to this light often do not realize they have been harmed until they notice resulting vision problems.

Fiber Laser Machine Glasses

We offer laser safety glasses and safety goggles. When purchasing fiber laser glasses, ensure that you select fiber laser glasses capable of blocking or reducing the appropriate wavelength range and optical density (OD). We provide a complete line of fiber laser glasses that protect the eyes from class 4, 7, and 8 laser systems.

Laser Glasses

Fiber laser welding is one of the most advanced industrial welding methods, widely used in various industries due to its high precision, increased productivity, and reduced need for consumable materials. However, this technology poses serious risks to the eyes due to the powerful laser beams generated by various manual and automatic laser welding machines. The use of laser glasses plays a crucial role in protecting individuals’ vision.

Risks of Fiber Laser Welding for the Eyes:

The eyes are exposed to several types of hazards during laser welding:

  • Laser Radiation (Ultraviolet, Visible, Infrared): Fiber lasers typically operate in the 1064 nanometer wavelength range and can cause serious damage to the retina. UV (190-450 nm) and IR (800-1100 nm) rays can lead to permanent damage if not adequately protected.
  • Scattered and Reflected Rays: Unlike traditional welding, severe reflections from shiny metal surfaces can be hazardous even for individuals not directly working with the laser.
  • Heat and Intense Light: The high intensity of laser light may result in burns to the cornea and retina.
  • Infrared Rays (IR): These rays can cause damage to the eye’s lens without pain or initial symptoms, leading to cataracts.

International Standards for Laser Welding Glasses:

To ensure safety, fiber laser welding glasses must be designed according to international standards:

  • ANSI Z136 (American National Standard for Safe Use of Lasers): Establishes specifications related to eye protection against different types of lasers.
  • EN 207 (European Standard): Evaluates the resistance of protective lenses against laser beams.
  • ISO 11553-1 (International Organization for Standardization): Provides safety regulations for laser welding systems.
  • OSHA 1926.102 (Occupational Safety and Health Administration): Addresses eye and face protection in laser industrial environments.

Optical Density (OD) Standard for Laser Welding Glasses

  • OD8: For wavelengths of 800 to 1100 nanometers (protection against IR beams and fiber lasers)
  • OD8: For wavelengths of 190 to 450 nanometers (protection against UV rays and some specific lasers)
  • OD7: For wavelengths of 780 to 1070 nanometers
  • OD6: For the 1064 nanometer range (Nd:YAG and fiber lasers)

Laser Welding Glasses

Laser welding glasses filter specific wavelengths, providing the appropriate optical density (Optical Density – OD), sufficient visible light transmission, and utilizing absorbing materials to prevent exposure to direct, reflected, or scattered laser radiation that could harm your eyes or even cause blindness. Compliance with standards and having the necessary certifications mentioned is also of high importance.

The OD of laser welding glasses is a parameter indicating the level of attenuation of laser light. Laser welding glasses must have sufficient OD to reduce laser light to a safe level for the eyes. The higher the OD, the greater the protection.
